I have a problem logging into my cpanel. each time I try to login it tells me my IP address has changed as in the image below.
enter image description here
The issue of
IP address changed
is most common with the MTN ISP for most of us trying to access webhosting providers. These providers are usually configured not to allow certain type of proxy connection. The MTN ISP sometimes acts as a proxy connection causing the webhost to deny access and redirect the request with the message
IP has changed
. To remedy or bypass such situations the following fix applies and works for me.
Download and install Thor Browser. From my explanation, follows Thor browser in circumventing the MTN ISP phenomenon.
Configure the browser such that your connection isn't being proxied.
Launch the browser and enjoy your Hosting services at full strength over your 3G/4G connection.

I have windows 10.
To get the IP address of some website I type ping somewebsite.com in cmd.
For example if I say ping google.com, cmd shows Pinging google.com [216.58.206.206] with 32 bytes of data: and some lines after that. If I type that IP provided (216.58.206.206), that gets me to Google.
But some websites aren't like this. For example for website codeforces.com I get 213.248.110.126, but this doesn't get me to the website, instead shows some error 404 Not Found .
Why it doesn't work and what is the best method to get IP addresses of websites in Windows 10?
Thanks.
Some websites cannot be accessed by IP only.
Think for example, a public (free or paid) web hosting, with shared IP. If you doesn't provide a domain name (FQDN), then the server doesn't know what page needs to be served.
Think also on some "public" services, like Azure DevOps. They provide you a FQDN over a microsoft domain, but probably each DevOps repository doesn't have their own IP. If you only provides the IP, then the service doesn't know what page are you requesting.
Also, if you enter to an HTTPS page, the certificate are securing the domain name, not IP address. If you try to enter with IP only, your navigator tells you the page are not secure (Try it with Google for example).
Forgive me here, I am largely post-technical for 10+ years and taken this as far as I can. I can probably take any advice and run with it, but may ask for some specifics to help if troubleshooting tools or commands are required. So please forgive that too.
Background:
Yesterday we could hit site URL after restarting VM hosted on Google Cloud. Sometime overnight, the URL was inaccessible.
Message:
This site can’t be reached <URL> refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
Troubleshooting:
can load using IP.
The technical guys (3rd party suppliers) insist they have not made any changes. My team have not made any changes.
The domain is still valid (it renews tomorrow)
The domain is used for the DEV environment with DEV as a prefix hosted on another VM.
Looking at firewall rules, all the rules with the proper tags appear to be set up correctly for HTTPS with appropriate IP (0.0.0.0) and port 80.
Many thanks in advance for your help. When I find the answer, I will post it here.
RESOLVED:
ROOT CAUSE:
During setup on GCP, the team forgot to link the reserved external IP address to the VM. As such, the external IP address was ephemeral so after a reboot of the server, Google issued a new external IP for the VM.
SOLUTION:
Reserve a static external IP Address and link it to the VM or promote an existing ephemeral external IP Address.

On Friday I hosted a WordPress site on my micro instance - I installed LAMP stack, and WordPress on it.
Instance state is Running, but when I try to access website with public domain given in console, it says
web page Not available
I have set an Outbound rule to allow everyone and Inbound rule for my IP address only.
This is about accessing website from outside world, but when I try to connect to my instance with JAVA Interface, MindTerm Web SSH, it says
Network connection timeout error
Can't figure out anything, Just started working on AWS.
I think you have confused the Outbound and Inbound rules - Outbound means traffic going out from the server, while Inbound means traffic from the internet to the server.
As you say, you added an Inbound rule for your IP address only, and you can access the website from you IP only, just like you requested.
Add an Inbound rule for port 80 for0.0.0.0/0, and you should be able to access the site from other locations as well.
If you need to open it to HTTP and SSH, open it for both for 0.0.0.0/0:
Please verify your settings and permission based on this :
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html
You might also want to check your firewall, in case that is blocking the access..
We have deployed our website to the live webserver, Windows Server, IIS 7.5. Website asp.net, .NET 4.5
I have configured the website bindings to allow https requests for this website.
Asked the hosting provider to open up the port 443.
I can access the website over internet with port 80, no issues at all. (http://mysite.com)
But I can not access via https, (https://mysite.com).
But I can access the site via SSL from the server itself, that means SSL configurations are fine.(https - localhost)
But I can telnet (telnet mysite.com 443), it responds to GET request via telnet.
I have rechecked the certificate and changed it to a self-signed certificate, issue is still there.
These requests not being tracked in IIS logs as well, seems like the request is not reaching IIS. Hopefully something goes wrong before it reaches the server.
But, when I access the website as http://mysite.com:443, it works.
I m bit confused with this behaviour. Obviously the port 443 is open by the hosting company. But something is wrong with requests over HTTPS, which is supposed to send a request to port 443. Please help.
Because your site is working when you access http://mysite.com:443, I am almost sure that you created wrong binding on IIS. Instead of selecting https from combo box you selected default http.
There is a tutorial on how to do this on youtube: Changing IIS 7.5 Bindings by David Johnson
You've establish that the port is open and the hostname binding is there, otherwise http://mysite.com:443 would not work. Its the SSL part that's not working, hence you can connect directly by port and telnet (port 443 but not SSL) but not a browser via https. It's only a browser connecting to a https url that will expect SSL.. I'm pretty sure I've had the same issue, but cannot recall the exact cause but it was definitely related to an invalid SSL configuration or SSL binding.. The behaviour was like there is no connection, nothing, which is unusual, its the bad config causes the browser to abort the connection. If I remember what, I'll update or comment below.
So you can access the site using https://localhost? Your question is not quite clear on this point... what is the exact URL you are using? If it's https://localhost, that is actually an indication that your certificate is configured incorrectly. You seem to be interpreting this as an indicator that it's working OK and that is not the case. The domain name is tied to the certificate and SSL will work only when accessing the site using that domain name. So if it works for "localhost", something is wrong.
Finally I found the solution. Issue was a setting in the load balancer of the hosting provider. I have asked the question from them and they have figured out the issue. Anyways it was a good learning curve for me. And this knowledge is going to help others.
The firewall was already allowing both HTTP/HTTPS, which is why we could telnet through and run a GET / and still pull down content from the 404 page of the IP address.
It appears there was a certain profile applied to the HTTPS configuration in the load balancer which would only work for HTTP, so they have disabled that.
When they set this up for HTTP and HTTPS they were not able to test HTTPS, because to do so would require an SSL certificate in IIS - which it appears we have already provided.
Thanks everyone for your help on this!
I'm wondering if anyone knows how this happens? My website is down, but every computer on my internet connection/router can see it. I've cleared my cache etc, but another computer in the house shouldn't be seeing a site that's offline. How weird?
It's hosted remotely, not on my network or anything.
The first question to ask yourself is, how certain are you that it's down? If computer A can access it and computer B cannot, either one could be "right":
The site could be down, and computer A could be looking at a cached version from the ISP.
The site could be up, but computer B could be having general internet connectivity problems, or problems accessing this site in particular (bad DNS cache, etc.)
One way to tell is to add some new content to the site (via FTP or an in-place content management system like wordpress, for example) and see if the computer that can access it (computer A) can see the changes. If so, then you're looking at a "live" site, where the pages are being served directly from the server. (If the server is active and runs web software like PHP or ASP, then that would be another way to "prove" that the site is up and running).
Do you know the IP address of your web server?
Do you have direct access to the Internet on port 80?
Tell if your server is up or down by doing the following
telnet 255.255.255.255 80
Where 255.255.255.255 is your web server's IP address. On windows the screen will go blank if the server answers. Then type
GET / HTTP/1.0
And hit enter twice. You should see the content of your default page. If your running as a virtual host, you'll probably need to use HTTP/1.1 and the Hostname tag.
GET / HTTP/1.1
Host: www.yourservername.com
There is one return after HTTP/1.1 and two returns after your hostname. If you get content (the correct content) back from your web server it is definitely not down. If the server fails to connect then your web server is really down, and the content your computers are seeing could be any of the following:
local page cache
local proxy server
ISP proxy server
local ARP poisoning attack redirecting you to attacker's local web server which mirrored your site.
DNS poisoning to direct your browsers to someone else's web server which mirrored your site.
If your site is up, but geographically separated folks can't see your site, it is most likely a DNS issue or an ISP level routing issue.
A good tool to check for DNS issues is OpenDNS's CacheCheck. As for the routing issue, the best bet is to call your web hosting company and see if they've had any other complaints from their other customers, or if they are currently working on a routing issue.
Internet provider cache maybe.
What DNS servers are your friends using? Same as yours?
Your ISP is probably caching the content.
i know it's down cause i asked my friends in other locations to look at it. then i ran a test using this site i found.
http://www.websitepulse.com/help/tools.php
i'm switching hosts and we're dealing with my main domain name. that's the other reason i expected this interuption. i just want to know when it's finally switched.
is ISP cache a bad thing?
