For the last couple of days, I've been drowning in the 502 Bad Gateway - nginx errors only in the AndroidCentral Forum, accessing individual threads using Firefox on my laptop.
I don't see the problem with IE. It stopped for a bit this afternoon, but is back about 100% again tonight. I also noted that access via Tapatalk has be a bit flaky for about the same period. I don't see any actual error in Tapatalk, just extended "Receiving from Server" loops that I often have to clear out manually to proceed. I originally attributed it to server overload with all of the action following the Droid X Froyo update, but now I'm not so sure.
Oops, just noticed the earlier entry RE clearing out cookies. I tried it, and it seems to be working for now.
