I was unable to get connection that would allow a log-on from 12:33 AM this morning on Comcast or ATT wireless on any of my devices. My Girlfriend's Verizon was out even earlier. None of the DNS fixes solved anything in my location for any of the devices, so I couldn't answer until the DNS resolution system came back up and I could once again log in. The problem seemed to be very sporadic and dependent on geographic area more than it did carrier.
I had this happen a week or two ago, where I just couldn’t log in. Or I would log in, I would then hit “Continue” and then it would take me back to the log in page, over and over. Or, I would finally log in and would be on a thread, try to post something, and it would log off instead and I lost all my post.
I cleared the caches and turned off AdBlocker, and was able to log back in, but it was hours later. Then I had it happen again sporadically over a couple of days, but since then it’s been okay. I wonder if it’s a virus.
