Server Version#: 1.22.2.4282 Player Version#: Android 8.15.2.24006 (same issue with 8.16 beta) After setting a custom SSL certificate, playback is broken on all Android apps. Web app works fine everywhere. Android app logs in, displays library, but fails when attempting to play a video: [FFmpeg] …

After considering how the Plex client is behaving, I found a simple solution. When the Android app starts, it tests the various connections methods to see which works. Unfortunately it prioritizes *.plex.direct before the custom domain. Then, even though the SSL certificate is invalid on *.plex.dir…

It has occurred to me that the SSL error with the *.plex.direct host name is due to the fact that my external port 50000 is being proxied to Plex with my custom domain SSL cert on the outside. I was originally under the impression that using a custom SSL cert in Plex would mean that the *.plex.dire…

Do you have Remote Access enabled? That sounds like a stupid question, but bear with me. :slight_smile: With a reverse proxy, I think you want it disabled. I think when it’s disabled, Plex doesn’t (attempt to) register an Internet-reachable *.plex.direct hostname. (I keep investigating this beha…

That’s a good point… I’ve always had Remove Access enabled. I’m not sure what security implications would with it disabled since Plex is handling authentication and not the proxy. I’m also not sure if Plex would even register my custom domain for external clients with it disabled? At this point, no…

I’m 99.9% sure that Remote Access doesn’t change anything related to authentication. I’m 99% sure that Remote Access does these things - Enable UPnP/NAT-PMP (Whether using default or custom ports) Perform Internet address detection Perform reachability detection Register the detected Internet …

I’m having this exact problem. Couldn’t figure it out for the life of me until I narrowed it down to removing the custom SSL certificate and custom domain from my server settings. Then everything in my Android phone started working again from outside the network. Then I came across your thread and …

BTW, I did test things. With remote access DISABLED and my port forwarded manually, custom SSL certificate enabled and custom domain filled it, things still do NOT work from outside of the network I looked at the generated XML and the *.plex.direct utilized ends up being the internal private IP ad…

I’ve started a similar thread as I cannot for the life of me figure this out: [image] Unable to play anything on any Android TV Devices Plex Media Server Honourable mentions: Android app not connecting to custom SSL domain - #8 by invar Hey guys! I have seen this mention…

[image] dkr88: So the solution is to make sure that the connection to the *.plex.direct domain fails at the http level. My proxy was configured to allow all connections on my external port regardless of host name, which was a mistake. So after limiting the connections to only my custom domain on…

Yup, that’s right. I use haproxy, so that’s just an ACL rule to only allow my custom domain.

[image] dkr88: And incidentally, the whole reason for needing the proxy in the first place is because of the fact that we can’t override the public IP for external access. So on Synology, Plex will use the IP address of a VPN if connected which again results in an invalid *.plex.direct certifica…
