Hi eungjun.yi,
Thank you for this... unfortunately when I copied the let's encrypt generated certificates to the locations below, I couldn't access MM
/home/myuser/mattermost-docker/volumes/web/cert/fullchain.pem
/home/myuser/mattermost-docker/volumes/web/cert/cert.pem
/home/myuser/mattermost-docker/volumes/cert/privkey.pem
/home/myuser/mattermost-docker/volumes/cert/key-no-password.pem # this is just a renamed copy of privkey.pem
Do you know what I'm doing wrong?
