How is it possible to downgrade my PMS to 1.42.xxxxxxx (before new ffmpeg has been added) as the world was great that time?!
NAS: ASUSTOR
MODEL: AS7010T
PMS: latest Version ()
Problem:
1. Where to find old versions able to be installed on my NAS?
2. How do I downgrade to that old version on my ASUSTOR as I am expecting that an manual install through ADM-software-install won‘t work?
Thanks

What are the issues that you’re having with 1.43.0?
1. Did you install from the Asustor store or did you manually install PMS?
- There may be previous installs here: `/volume1/Plex/Library/Plex Media Server/Updates`
2. You need to remove the existing PMS first. After that you can install 1.42.xx.
- Removing the PMS app just removes the install, not your media or server data files.

All streams since 1.43.xxxxx are not running smoothly and it doesn‘t matter if movie and/or show.
OttoKerner mentioned that new ffmpeg has been added so that might cause troubles.
That‘s why I would like to downgrade …
Install from ASUSTOR-store but no chance to find previous versions compatible with ASUSTOR
Sure that only the app will be removed?

100%! Just removed and installed on an Asustor I have with me. In most cases if the uninstall or removal from a NASs store is destructive, they’ll provide a warning prompt.
I couldn’t immediately find the previous 1.42.x builds. I’ll have to ask around.
In the meantime could you please do the following;
1. Confirm server [DEBUG logging](https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/#toc-1) is enabled, VERBOSE logging is disabled.
SAVE if changes.
2. Restart PMS
3. Give it two minutes to start and stabilize
4. Start a playback which shows the issue
5. Let it play for 20 seconds
6. Stop the playback
7. Download the [server logs](https://support.plex.tv/articles/200250417-plex-media-server-log-files/)
8. Attach the logs so I may see them.
I’d like to understand what’s happening that making such a bad experience.
