Hi On several occasions I have now been logged in as a different user in the midst of scrolling a thread. It has been the same user each time. We both have admin privileges. There’s nothing in the logs.

Been a while but it happened again. Changed user real time as I was scrolling a thread. However, my profile picture was still on the top right and clicking it led to my profile, despite being logged in as the other user. Seemingly I got added to the same login session as his android device. The …

This continues to occur randomly to any and all users. It hasnt happened to me but I did get signed out when it happened to someone else once. I have no idea where to even begin looking. I have a thread going on my forum that I made public to provide more information. This time 2 users became logge…

@Falco this is an ongoing issue for several years now. As far as I know this is an issue with the client side user session and the userID specifically.

I can understand the lack of support. We arent paying customers and some of us arent even being very nice. I dont blame you for pointing the finger at me as I agree, its something I’m doing different that causes this headache. If you genuinely believe the reverse proxy is whats causing this issue th…

[image] Chris Kennedy: Do you think thread size could be causing this? Some sort of side effect of an overflow/overrun? We run forums where topics go way over 70k replies and this haven’t caused this issue, like Forum Jeux vidéo - Gamekult or Woot [image] Adubs: If you genuinely believe…

[image] Falco: But if it only happens on this specific instance it is a security issue on your site, and not on Discourse, right? If my reverse proxy is able to mangle some token or whatever in the right way such that discourse believes a user has become someone else… does it really matter if…
