The "session expired" error

I keep getting "session expired" constantly in my games, making them unplayable. I will log in, run the game for a few minutes, and then try to open a sheet and get the error. From that point, the only thing I can is a full computer restart, log back in, and play for a few more minutes until the session expires again. I have:  Tried in both Firefox and Chrome, both in normal and private/incognito mode. Deleted and removed data for all addons and extensions for both browsers. Cleared all cookies and my cache. Changed my DNS to Cloudflare and Google. Allowed roll20 through my antivirus and malware software Tried a VPN These are all the things that support said to do, and absolutely nothing has worked. Am I just not able to use this website? I see other people having this exact same issue over the past few years, and they get the same advice as I have, and it never seems to fix anything. What am I supposed to do here?

Interesting discovery. When I had this forum post open and opened my game in another tab, I checked a sheet and the session was already expired. Tabbing back to here showed me as logged out, and I had to log back in post this reply.

Hi Sandwich,  Considering the steps you have already performed (thanks for listing them) I suggest filing a report with the Devs. You can do that via the Help Center . 

The steps I've taken were the ones suggested by the devs from the report I already filed through the Help Center.

Did you let the Devs know they didn't work? What has happened with the ticket since then?
