My mattermost server (mattermost-5.14.2-linux-amd64.tar.gz) was running smoothly hosted in my own vps running under Ubuntu 18.04. I could also access it using Android and iOS mobile app until yesterday.
Today I couldn’t able to login to my server at all. i.e. when I login to my site http://example.com:8065 the username & password is not showing like before as per per the picture below:
If somebody can help me as to understand what must have caused this issue would appreciate!
Thanking in advance.
