I have a self hosted mattermost instance. I previously had it set to use TLS with self signed certificates. I want to employ LetsEncrypt to do the TLS.
In doing this, I felt it probably better to go from TLS to None to LetsEncrypt in those stages , and testing in each stage as to be cautious.
However when I went from TLS to None for the connection security, I was no longer able to log in to the server from the client app or the browser on the client, with the message stating “session expired”. I was sure to make certain that the Server URL and the listening port was set correctly. I also reset the password to see if I could get in with a new password.
Is there a simple explanation and workaround for this issue ?
Any help will be appreciated
