Server Version#: 1.29.2.6364  
Player Version#: 1.29.2.6364

I have changed so many things the last couple days trying to correct whatever it is I messed up. My remote access was great up till the day before yesterday when I was trying to tighten up the security on my headless Ubuntu Server.  
Ubuntu Server  
Dell T320 Server  
Verizon 5G Home internet (White Cube)

Ive tried:  
Setting the port 32400 manually - did undid redid - no help  
Enable/disable UFW - did allow the 32400 port  
Installed/uninstalled Fail2ban  
Installed/uninstalled RKhunter  
Installed/uninstalled Jack/John the ripper  
I did other security things but honestly can’t remember what all I did.

I’m considering trying to reinstall the Ubuntu Server over top. If anyone has any suggestions I’ll take them. I am not fluid in linux. I muttle through it LOL. Thank you.

EDIT to add: sometimes it will stay connected for several minutes, other times it won’t connect at all.

Verizon 5G Home Internet uses [CGNAT](https://en.wikipedia.org/wiki/Carrier-grade_NAT) Internet addressing, which is incompatible with Plex remote access.

People may be able to connect remotely using [Plex Relay](https://support.plex.tv/articles/216766168-accessing-a-server-through-relay/), which tunnels the stream through a server at Plex and is limited to 1 Mbps (2 Mbps with a Plex Pass).

[Plex Relay](https://support.plex.tv/articles/216766168-accessing-a-server-through-relay/) can be enabled via Settings → Network → Enable Relay.
