We are running Bitbucket Server 7.6.2 behind nginx. Nginx is handling all the SSL stuff. We have been running this configuration for several years with different versions of Bitbucket Server and has never had any issues.
Just the other day a user found that when he saved the changes made on https://<bitbucket URL>/plugins/servlet/notification/settings he got XSRF Security Token Missing. I have tried as an administrator and as a normal user and get this every time I save the settings.
I found a KB on XSRF Security Token Missing, https://confluence.atlassian.com/bitbucketserverkb/xsrf-security-token-missing-779171343.html. I have looked through all 6 options. Option 2 could have been a problem as we had the secure=true in our configuration. But removing it changed nothing. We only see the problem with the above mentioned settings save.
Any ideas on what might be the problem and how to fix it?
