Can anyone please help me with this?

Alfresco unable to connect to server http://mydomain:8080/alfresco

i am running alfresco on linux server i am able to access the files from back end but when running http://mydomain:8080/ it gives the following error
Unable to connect
Firefox can’t establish a connection to the server at mydomain:8080.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
tomcat is running but i still cant figure out what could be the cause of the error.
Could you take a look to a tomcat logs?. Maybe you can find more information about the issue.
Could you check compatibility of your amps files with Alfresco version?
Regards,
clv
First, try to hit the Alfresco webapp from the local server itself using curl, like:
curl -v -uadmin http://localhost:8080/alfresco
And see what comes back. If you get a 200 or a redirect, try Share next, like:
curl -v http://localhost:8080/share
If you get a 200 or a redirect then both web applications are working fine and this is due to a network connectivity problem between your client machine and the server or a firewall issue.
If curl cannot hit one of the web applications locally, you should inspect the logs ($TOMCAT_HOME/logs/catalina.out) to figure out why.
You can also "ps -ef|grep tomcat" to make sure Tomcat is actually running, and you can "netstat -atnp|grep 8080" to make sure Tomcat is listening on the port you think it is.
If all of the firewall and networking tests are fine and the logs have no clues, uninstall the AMPs one-by-one until it starts working again.

Socket.io is getting a 403 error on my website

Check https://www.winsteadworks.com console for the error.
My website is on my raspberry pi 3 using nginx webserver to host my website. I am having trouble getting NAF (Networked AFrame) to work correctly. What I am trying to do is get Easyrtc to work correctly so I can interact/communicated with other players on my website. I got this to work correctly while it was hosted locally on my other computer, but when I moved it to the raspberry pi and tried to put it online was when I started to have issues.
I am getting a 403 error for my socket.io for easyrtc. On my website if you look in the console you will see the errors start to stack for socket.io.
What I have tried:
Check port forwarded ports
tried to add port 8080 to my config in /var/www/html/winsteadworks.com but kept getting errors
Checked my firewall settings for both my router and my raspberry pi
I also tried reconfiguring different files but still have had no luck.
The error:
socket.io.min.js:1 GET https://winsteadworks.com/socket.io/?EIO=3&transport=polling&t=MJ1pNxu 403 (Forbidden)
This error continues over and over every second and won't stop until you close the page.
I am at a loss here until I know a few things:
Why am I getting this error? Is this a nginx issue, is this an easyrtc issue, is this a raspberry pi issue, or is it a port forwarding problem (yes port 8080 is forwarded)?
What direction do I need to go in order to problem solve this?
Or I will just take the short, sweet and simple answer! Thanks in advance for you time.

Nginx bad gateway 502 with piui

I got a problem with Nginx, it always shows "502 Bad Gateway nginx/1.2.1"
I am using Nginx on my Raspberry Pi with the software Piui.
Last time I used the pi it worked perfectly, now one month later suddenly it doesn't work. This is weird because I didn't change anything in the configs or in the Pi's system.
Does anyone have an idea?
I followed the PIUI Tutorial. Accesspoint works, can connect and ping from several devices.
I've searched for information, but can't find the issue.
As posted in the comments: Sounds like the sofware to which the request shall be proxied is not running, check if the piui-supervisor is running.

I have tried to access a website that i created in my xp machine that have iis 5.1 from the LAN , but without any success i have tried what is suggested in the following link How to access your website through LAN in ASP.NET , but also without any clue . I open my site in my PC(locally) like this "192.168.1.252/pse" and it works , but from other pc in the LAN , its not displayed at all.
Any Help will be most appreciated.

Is your Windows Firewall turned on?
You say, "its not displayed at all". What happens instead of it being displayed? Is there an error message?
Most likely, your firewall software is blocking external access. If external users can find your machine using ping, then that suggests a firewall is blocking access.
Please do what the two previous posts suggested, check to see if you can ping your computer from a different computer within the network and then check your firewall also.
When you are done checking the above suggestions, if you still have trouble viewing your page from a different computer, check to see if your computer has port 80 open. And if it is using port 80 and everything looks ok, please provide the error number you are receveiving, I am guessing it is 404 - Page not found.
Hope this helps!
It was firewall and Antivirus problem , they were blocking the port 80.
Thanks All for your Help.
