 This forces your client to use the Gogs-specific SSH key for every connection to [src.mehl.mx](https://src.mehl.mx) – and not the default one for this IP/server. However, this is only a problem for you as the administrator, not for other users. It took some time for me to find that out :)
 
 **Update**: It’s best to use the built-in server if you cannot create a separate user for Gogs and if you depend on using the default `~/.ssh/authorized_keys` file for other use cases than gogs (e.g. to log in). The problems lies in Gogs behaviour: sometimes it rewrites the `authorized_keys` file without being asked to do so, and as a result you cannot log into the user’s account anymore via SSH! To make the solution easy for you, here’s the excerpt of my `custom/conf/app.ini` file:
 
-```ini
+```text
 [server]
 START_SSH_SERVER = true
 SSH_PORT     = ${DEDICATED_SSH_PORT_FOR_GOGS}
