SSL installed and working, but setting Mattermost to SSL breaks it

[agriesser (Alexander Griesser)]

Hi @andriusba and welcome to the Mattermost forums!

If you already have OLS running with SSL, you do not need to set up SSL for Mattermost, all you’d need to do is make sure that https://lgms-mm.lt has a reverse proxy configuration to your locally running Mattermost instance on port 8065, that’s all. You also do not need to open port 8065 to the public, because the connection will be local only from your OLS to your Mattermost application server directly on the same host.

The only thing you have to change in Mattermost is the SiteUrl setting in your config.json, it has to point to https://lgms-mm.lt then.

Please check out this thread for a working OLS configuration a user shared with us and let me know if that helped you:
