I am not able to register to or ask questions at SuperUser from my office machine (same with registering at ServerFault - haven't tried asking questions there). I guess the reason is that I am behind a proxy server and is using DHCP. I tried to register at SU and SF from this machine for so long but it didn't work. Finally I tried from another machine that doesn't use DHCP and is connected to the proxy server with a permanent IP address, and it worked like charm. Now I tried asking my first question on SU from my machine and I got the same issue again.
At first I thought it was some internal proxy related issue but I am able to register/ask questions at SO and meta from the very same machine without any hurdles.
This is the error message:
The requested URL could not be retrieved
While trying to retrieve the URL: http://superuser.com/questions/ask/submit
The following error was encountered:
- Read Error
The system returned:
(104) Connection reset by peer
I've tried from Vista and Ubuntu, if that matters.
Just to clarify - SU isn't blocked here - I'm able to open the site and browse through all the pages, including the
Ask question one. I get this error when I type in the question and click submit. Similarly while registering, I am forwarded to the Open-ID provider and asked to login - but when I submit my details at Google and click login, the address bar shows su/authenticate (if I remember correctly) but I get this error after 5-10 seconds.
UPDATE: Don't know what the issue was, but it seems to be fixed now. I just asked a question on SU successfully.
