I have invited one of my brothers to connect to my PLEX media server remotely. For 8 months it worked fine. However now it does not work. He gets an error message to the effect “Cannot connect to media server.” I sent him another invitation, but the problem continues. I suggested that he uninstall the PLEX player from his LG Oled TV, then to reinstall it. He has done this, but the problem continues. I have verified that other remote guest users are successfully connecting, so the problem is with his system.
A few weeks ago his internet carrier, Frontier, came out to boost his fiber connection from 50 to 100 up/down. The Frontier tech rep also removed the modem from the premise saying his wifi system (Obi-something) does not need it.
My brother’s TV does get other programs, such as YouTube TV and YouTube–both in high quality. But nothing is working with PLEX.
What would you have him do to repair the system that until a few weeks ago was working properly?
