I’ll ask our devs to look at the error messages you’re seeing.
When will you reply from developers? I am looking forward to your response from the developer.
I would like to know more about the item “SecurityConnection”. Even if I use a proxy, is it necessary to enter “TLS” in this item? When I see the behavior of Mattermost, I seem to not use HTTPS completely unless I enter TLS. If I do not enter “TLS”, Mattermost seems to consciously redirect to “http”. However, when I enter TLS, I must specify the location of the file.
Currently I forcibly designate Plesk’s certificate from the outside of Plesk. In this way, I am anxious because I do not know when the relationship of certificate binding will be broken. I would solve another Let’s encrypt installation separately. But I think it is in vain from the viewpoint of server capacity.
CentOS 7.5.1 / nginx 1.13.8 / Mattermost 5.1.0 / Plesk 17.8.11
