I've had this happen once before recently on a different site, and I don't know what I did to fix it.
Now my computer will not open any page on
stackoverflow.com. When I try, I get the error message:
Gateway Timeout: can't connect to remote host
The connection was reset. The connection to the server was reset while
the page was loading. The site could be temporarily unavailable or too
busy. Try again in a few moments.
This is odd, especially because it doesn't seem to matter what browser I'm using. I'll encounter the error in Firefox, for instance, but then the same thing occurs a few minutes later in Safari. Or Chrome.
The connection to stackoverflow.com was interrupted
and at the bottom of the dialog:
Error code: ERR_CONNECTION_RESET
When I try to access the site from a different computer, no problem.
I've removed all cookies that I can identify as coming from
stackoverflow.com and quit and re-started the browser. No difference.
