My entire .ipynb file has one cell, running only print('hello world'), and still no luck. I make sure no other processes are running but this.
I tried reinstalling Python and disabling antivirus. I don't have Anaconda.
It worked before, I don't see where this problem is coming from. My only guess is me changing some IPv4 properties has caused this, though I've changed it back to how it was. I've searched and tried many solutions but still no good.
I also notice that the circle next to "Python 3" in the navbar is now black instead of white as before, and now it cannot bind to localhost.
Please help!
I fixed the problem.
Just changed the ip address in C:\Windows\System32\drivers\etc\hosts from
0.0.0.1 localhost
to
127.0.0.1 localhost
It's working normally now.

I have used WordPress on Cloud9 successfully previously, but I can't even get a new one to start via JetBrains IDE.
I have two machines: one Windows (XAMPP) and one Mac (MAMP) and getting the same "502 Bad Gateway" error when the browser tries to login to the WordPress dashboard page.
I downloaded a fresh WordPress copy, set up my database and ran index.php in the WordPress root folder. That does take me through the database questionary and up to the WordPress login page, and then the browser hangs there. It tries to load something and nothing happens. If I halt the browser and refresh, I'll get the 502 error and I'll keep getting this error on ANY OTHER files that I try to run from now on (it feels like something server-related breaks from within the IDE and I have to restart it).
The PHP 7 interpreter seems to be working fine, because I don't have an issue running any other of my non-WordPress projects.
The project address is http://localhost:63342/wordpress/, but I noticed this below link is shown in the PHP-CGI server window:
/Applications/MAMP/bin/php/php7.0.0/bin/php-cgi -e -b 127.0.0.1:56502
Does this PHP CGI pointing to a different port number mean anything? I am new to WordPress and it was a breeze starting one in Cloud9, but I just don't understand why it doesn't work in PhpStorm 10.
As I said, there is the same problem on two machines (Windows, Mac, MAMP, XAMMP, and PhpStorm), so I know it is me who's missing something here.
I recommend you use Varying Vagrant Vagrants WordPress (VVV).
It's a better solution and will help you achieve better results without too much hassle.
I would recommend you to use a simple editor like Sublime Text or Atom and install packages. I have personally lost many hours trying to get PhpStorm, MAMP, LAMP, and XAMPP work the way they should.
I managed to solve my problem. It was the port number causing it to crash. My MAMP port number is 8888 (XAMPP is 80) and when I set up PhpStorm a year ago on both machines somehow I entered 63342 as server port number!
This never created any problem for me whatsoever running dozens of PHP projects since then, but obviously, it mattered to WordPress (dashboard). I went to PhpStorm settings and corrected the port number so it matches MAMP/XAMPP and all is working fine now.
It was a pretty basic (and silly) mistake to make on my part, but that wasted two full days in which I could have been teaching myself WordPress and developing themes/plugins.
Yes, it worked for me after configuring the built-in server port to 80 (I have used XAMPP)

In top of my dashboard showing two errors...

thankz in advance
Assuming this is coming from a localhost installation.....
This is due to you having a poor internet connection. I see it often. All it does is slow down your localhost site while it searches for wordpress.org, and that is all. It is simply Wordpress checking the net for updates (and probably fonts as well).
It's just irritating, but no action is needed on your behalf.
I have solved this issue by adding the following line in the bottom of wp-config.php file.
define('WP_HTTP_BLOCK_EXTERNAL', false);
I fixed the error on Ubuntu OS using following steps
open terminal or(Ctrl+t) and type ping api.wordpress.org
Note the ip address pinging on the terminal. Close the operation by typing Ctrl+c
Type sudo gedit /etc/hosts and add above ipaddress followed by api.wordpress.org like this (198.xxx.xxx.xxx api.wordpress.org) in the host file
Hope this helps others who runs Ubuntu OS
Ok so this may be a dumb question or possibly something that just isn't supported but haven't had much luck finding an answer.
I'm testing out Light Table for use as my day to front end editor and have been trying to get a page loading in the internal browser without success. I have a weblogic server running my app which I can access from Chrome and other browsers but when I try to point Light Table's browser at the same url I get the generic proxy can't connect to destination.
My first thought was that this I needed to configure Light Table to work with the company proxy but I am able to get to other sites from light table using the built in browser and I have the env variables http/https_proxy set. Has anyone seen this issue or know of a fix/workaround?
Ubuntu 14.04
Light Table 0.7.0
Chrome 36.0.1985.125
It's weird but sounds "reasonable" that you don't really need any proxy to access localhost. I'd check using 127.0.0.1 in your url rather than localhost if you already didn't.
I recall a weird issue probably unrelated on Ubuntu that prevented the right name resolution. The resume is to check that /etc/hosts should contain just 127.0.0.1 localhost rather than your_machine_name 127.0.0.1

I used to run web applications all the time on my laptop, no problems, I am using VWD 2008 Express, i have the latest framework, Windows Vista Home Basic...etc..
Now, when ever i try to run a website, or even chose to Show a Page in Browser from Within VWD, the browser (both IE and Firefox) keeps looking for www.localhost.com...
I tried to copy the address of and paste it directly in the title bar, nothing, same problem i tried to get that address from the balloon notification (the one that pops up when you run any ASP.net project), still nothing happens...
My colleague is facing the same problem, but for him, he can simply copy and paste the url in the address bar, but its not working with me....Heeeeeellllllllllllllllp
Check your hosts file, it should be redirecting localhost to 127.0.0.1 and nothing else. The entry that will cause this error should look like this:
127.0.0.1 www.localhost.com
If you find this, remove it or change www.localhost.com to localhost.
You can also try to post one of these in the adress bar:
127.0.0.1
http://localhost
Note that the hosts file is a popular victim of viruses, so if is has been modified, you might run a check on viruses.
Also see the discussion here.
If that also doesn't work, open up nod32 (you probably have it installed on your system if the above methods don't work) go to advanced setup, on the left menu, select protocol filtering, and select HTTP and POP3 ports... ;)
I got the same problem in firefox 3.6 when my server was down.
In my case it was not a problem with etc/hosts where the line
127.0.0.1 localhost
was there and OK.
The solution that worked for me was to disable the "cleaver" URL fixing that Firefox carry out when the page is not found. The procedure taken from here:
Type about:config in the address bar and hit return.
find browser.fixup.alternate.enabled
double click the “true” value. The line will become bold, and the
value will change to “false”
This fix directly the problem. No firefox restart needed. If your server is down you get "page not found" as expected.
Hope it helps.
Thank you for your solution ... this works fine...

A couple of random things to check...
localhost is the conventional name for the IP address 127.0.0.1. If that address doesn't work, then you have a network configuration problem.
There will be a hosts file somewhere, probably in somewhere like C:\Windows\System32\Drivers\Etc\hosts which should usually contain only that definition for localhost. If it has more names in it and you didn't put them there, then you have another problem entirely.
There is also the forehead-slapping possibility that your web server is not currently running. :)
My development machine (Vista) was working perfectly fine for over a year and then suddenly (without explicitly installing anything) I am unable to run the websites using ASP.NET development server.
The development web server starts fine, but IE cannot display the page:
Internet Explorer cannot display the
webpage
Firefox says - Failed to
Connect, The connection was refused
when attempting to contact
localhost:49447.
Here is what I have tried so far:
Disabling firewall
Stopping anti-virus
Stopping Windows Defender
It worked when I stopped all services using MSConfig and tried again.
However, that disables most of the services, so is not a feasible long term solution.
After stopping all services, I tried starting services one by one to find out which one is causing problem.
These are the steps and results:
I found DNS Client Service was
causing problem.
So I started all others and
stopped DNS Client service, but then
Network Location Awareness service
started causing problem
I stopped DNS Client Service and
Network Location Awareness and
started all others, btu again
something else is causing problem.
Clearly there is something common and fundamental at the root of this.
I do not know much about networking. Can someone guide me in right direction?
Note: I have found another person who
is having same problems since this
morning. Looks like it could be
related to one fo the windows updates!
Is anyone else getting affected like
me?
I was able to fix this on my computer by doing the following:
My host file contained this line for the localhost entry, which is how the host file ships with Vista, and i've never modified this line
::1 localhost
Replaced "::1 localhost" with the this:
127.0.0.1 localhost
"::1 localhost" has worked fine for me for well over a year, until this morning. Windows defender installed two updates, one yesterday and one this morning, my guess is that something in one of these updates caused this entry to not work anymore.
I have solved this problem.
The problem comes because somehow the entry in host file is removed for localhost.
you have to add entry in host file which is kept in System32/etc folder.
just add this at the end of the file.
127.0.0.1 localhost.
save this file and try to ping localhost from cmd prompt.
i think this will resolve your problem.
now try running you website.
All the best.............
If stopping all the services made it owrk, try stopping one at a time. Eventually you will find out which one it is.
Hopefully someone will know which it is from experience, but if not you can find it yourself.
Sounds like you have a proxy server issue - have you checked this out?

I also started to get this problem tonight, think I installed a windows update package yesterday.
I'm running VS 2008 (9.0.30729.1 SP) and Vista Ultimate SP1 (32-bit).
Replacing localhost with 127.0.0.1 worked for me.
http://localhost:49227/testsite/Default.aspx
http://127.0.0.1:49227/testsite/Default.aspx
I'm having the same problem. Was working on my website last night, one minute the site worked in the broswers next minute it could not connect to the localhost.
Replacing localhost to 127.0.0.1 worked for me. I'm still inexperienced in asp.net, is there a file where you change
http://localhost:49227/testsite/Default.aspx to
http://127.0.0.1:49227/testsite/Default.aspx
As I am just changing the url in the browsers
This one also worked for me. What I did was:
Go to the Property Page of my Project.
Then under Start Options, look for the Server, instead of 'Use default Web Server', i changed it to 'Use Custom Server'.
Typed the http://127.0.0.1:49227/MyProject/ in the Base Url.
That's it. It automatically opens the site using this link.
Same problem here using visual studio 2008 express
Changed "localhost" to "127.0.0.1" and the page came up.
This problem seems to have an effect on internet explorer and firefox
Opera hasn't seen this problem :-)
Grtz
Changing "localhost" to "127.0.0.1" worked well for me, as well.
but just to clarify the whom are not familiar with vista here are the guidelines to change:
Browse to Start -> All Programs -> Accessories
Right click "Notepad" and select "Run as administrator"
Click "Continue" on the UAC prompt
Click File -> Open
Browse to "C:\Windows\System32\Drivers\etc"
Change the file filter drop down box from "Text Documents (.txt)" to "All Files (.*)"
Select "hosts" and click "Open"
Make the needed changes and close Notepad. Save when prompted.
The problem comes because somehow the entry in host file is removed for localhost.
you have to add entry in host file which is kept in System32/etc folder.
just add this at the end of the file.
127.0.0.1 localhost.
save this file and try to ping localhost from cmd prompt.
