Would you be able to share more details on your TLS configuration you have applied on your instance?

Hello, @aballester

On top of the TLS configuration asked by @amy.blais, I took a look at the mattermost.service configuration and compared it with the default systemd unit file in the official documentation. I noticed a couple of differences here:

[Unit]
Description=Mattermost
After=network.target
After=postgresql.service
Requires=postgresql.service

[Service]
Type=notify
ExecStart=/opt/mattermost/bin/mattermost
TimeoutStartSec=3600
Restart=always
RestartSec=10
WorkingDirectory=/opt/mattermost
User=mattermost
Group=mattermost
LimitNOFILE=49152

[Install]
WantedBy=postgresql.service

When compared, I noticed the following lines were commented out. May I know if there is any specific reason behind that?

#After=postgresql.service
#Requires=postgresql.service
...
#WantedBy=postgresql.service
WantedBy=multi_user.target

Just want to make sure that we don’t miss out on the little details. Also, can you run steps 10 (c-g) based on here and share the results of each step that you see on the terminal? For example:
