In recent months things have been more reliable, so would imagine you or your identify verification provider has resolved or tinkered with things or settings.
I do occasionally get situations where things time out, or the redirect/forwarding just fails. ie you get to a blank screen, says it's confused or you refresh and it claims to have no idea what the request was. You end up going back and forth to the originating page/post and it either succeeds as now it thinks I'm logged on, or it repeats the log on process. Like I said it's mainly in the redirect via the login, and even if that completes quickly. Some times I think the quickness is the problem, fields auto-fill and I bang the login button.
Occasionally when trying to reply I get complaints about credentials, the Red Box error warnings, and that generally means the system has logged be out.
Other times if I cut-n-paste stuff out of other posts I get an HTML warnings. Sometimes hitting Post again works as it re-rendered or processed the post internally. Or I just need to re-paste using "without formatting". Mostly with things where it looks like it's Quoting, or Code Blocking something I've pulled from within the rendered frame for the post/page.
