After a months usage, I’ve (suddenly) become unable to login into my Umbracy 7.25(I installed 7.2.4, then did one upgrade without issues).
When accessing the Admin user interface, I get a glimpse of the backend but it then immediately sends me back to the login page with a Session Timeout.
The logs write “Login attempt succeeded for username” for both servers. Occassionally, I will get logged in but once I click anything, I get sent back to login. Firefox for some reason seems to be able to handle this slightly better, so I at least browse around the backend with about 10-20 logins per page.
I’ve not used the server farm web.config settings and its installed on two servers. Despite it working fine for nearly two months, could it be related to these settings?
According to my hosting provider, they didn’t change anything. And I didn’t change anything either between it working and it stop working.
But likely, something did change. Any hints to where I can look?
Its still working fine in STG and DEV environments which do not have multiple webservers.
