Found a few things.

  1. The certificate you added is not working. The error indicates either bad password, incorrect SSL algorithm (Plex requires SSLv3)

Here is how to make your certificate.

  1. The database is damaged

The recommended fix is to substitute one of your backup DBs in to use as current

I wrote a tool which will help you do this (DBRepair), specifically the Replace command

Since your server does minimally run (the container starts), I would place DBRepair under /config and run it from inside the container (docker exec style) where it can detect which image you’re using and auto-configure the paths itself.

You can try to use the “Auto” function first but given the Index is malformed, it may not work.

That failing, REPLACE is your best option to recover.

  1. Since your LAN appears to be IPv4, you can turn off IPv6 support in Settings - server - Network
