Manually add Plex DDNS remote access?

`Since my PMS does not pick the correct public IP once in a while, I would like to help it manually. I have a DDNS which I would like to add as a remote access configuration. where do I put this?

best wishes!

Custom server access URL

Keep in mind that you’re going to need a fitting security certificate for this domain name, if you want it to work with “secure connections”.
