I disabled DLNA and GDM on Plex just now. Not sure how to remove that port, but if a newbie to it all.

Install portainer throigh plexguide.
access portainer through port 9000 or sudo main.
Set up your user, connect locally.
Click containers, locate plex container.
click edit, find the bit that's says port 1900, press the delete button and then press deploy on the plex container

Emby caused the same problem for me as I forgot to disable the DLNA/Blast alive messages.

After you've fixed it reply saying that you've resolved the issue. That should be the last you hear of it.

Yup, I got the same email this morning as well. I was about to do the same thing, disable port 1900. I'm glad others here verified that's the right thing to do.

Sorry to bring back alive an old thread but I just got one of these and this is still the correct thing to do ?
