Thank you, that resolved the issue.
*Edit to add:
When I tried to log in, it gave me an error that it could not find the following page:
Which is understandable... my firewall is blocking that port and my reverse proxy (nginx) is serving this. But why does this happen? When I press back, it takes me to the actual page, but a lot of "session mismatch" errors pop up. And when I log out and try to log back in, then I have the same issue? I am doing this from work, but at home, I don't have this issue.
**Edit to add again:
I tried again, the session mismatch is not there, but the same issue reoccured.
"This site can’t be reached
localhost refused to connect.
Search Google for localhost 4567"
This used to work, before I updated nodebb, so it can't be a nginx issue.
When I go back to my page (again) and log in, now it is fine. I will try logging out and back in again.
Nope... session mismatch again, up until I close the browser and try again. So this is a endless loop of session mismatches.
