Server Version#: 1.25.3.5409 (docker) Sonos Version#: S1 11.2.13 My issue is the same as the ones shown in these threads: > [@Sonos: incomplete TLS handshake: no shared cipher](https://forums.plex.tv/t/sonos-incomplete-tls-handshake-no-shared-cipher/746087): > > Hi everyone, Thanks for having me. I am running the following configuration: Server Version#: 1.24.3.5033 (as docker) on Ubuntu 20.04.3 LTS (GNU/Linux 5.4.0-86-generic x86\_64) Player Version#: Sonos Connect S1 I have the same problem as mentioned in the following closed thread: [https://forums.plex.tv/t/sonos-incomplete-tls-handshake-no-shared-cipher/699668/10](https://forums.plex.tv/t/sonos-incomplete-tls-handshake-no-shared-cipher/699668/10) Sonos this week suddenly (from one day to another) stopped playing songs from the Plex media server.

I can still browse the library from Sonos apps, but when I try to play the song it doesn’t work, Plex logs shows: Mar 12, 2021 21:44:59.550 [0x7f24f3fff700] DEBUG - CERT: incomplete TLS handshake: no shared cipher Any ideas? Update Did some more digging. Plex seems to supports the following ciphers… Starting yesterday (right after Plex updated to 1.25.3.5385) I am getting a message in the Plex log like this whenever I try to play something from Plex via Sonos: `CERT: incomplete TLS handshake from [::ffff:192.168.2.254]:41209 no shared cipher` Disabling TLS on the Plex server works, but I would prefer not to leave that off. Does anyone have any other ideas? There was a comment in an old thread about Plex changing certificates to be RSA based, but I don’t know what ever happened with that. @johnclayton Any update on that? I updated the Plex container to 1.25.3.5409 this morning, but unfortunately that didn’t seem to help. I have an old Play:5 Gen 1 so I can’t switch to the Sonos S2 app. ---

Something else I just noticed when digging through my logs. It looks like the port requested in the error message is random and changes for each request. Is that expected? I noticed it’s not the 32400 that’s required to be open for remote access to work. The IP address appears to be the IPv6 version of my gateway’s IP. ---

In your server settings, Network, make sure that `Strict TLS configuration` is disabled. If that doesn’t do the trick after restarting PMS we’ll probably have to wait and see if @vanstinator has any input. ---

Yes, I know that disabling TLS will make it work. I just don’t feel that “turn off the security” is an acceptable solution. ---

This isn’t turning off security. Hell, I don’t even allow non-secure connections for my parents’ crappy old “smart” TVs. This just allows a more permissive secure connections for clients that don’t support current standards. IIRC Sonos and some other clients were the reason this setting was added. More info on it [here](https://support.plex.tv/articles/200430283-network/). ---

Ah, I thought you were referring to changing Secure Connections to “Preferred” or “Disabled”. Disabling “Strict TLS configuration” doesn’t let Sonos work, same errors as I posted above. ---
