Minimstreamer 'Chain: error running chain'

[MDF]

I have lost the ability to use local streams like http://192.168.0.74:9790/minimstreamer/*/paradise radio.

The minimserver log says 'Chain: error running chain'. I have made no recent changes to my configuration or playlist files. All the actual stream addresses still play ok. I assume this must be connected to recent minimserver or streamer updates somehow?

I have exactly the same issue Minimstreamer 'Chain: error running chain'
None of my minimstreamer streams are working since the latest minimstreamer update.
My server is running Ubuntu 22.04 and I have not changed any config files. Looking at debug logs, the streams are being found and the transcoding required is recognised, but nothing gets streamed and the log shows "Chain: error running chain"
My license is still valid until Feb 2026.
Minimserver is still streaming non transcoded files just fine.
Help please.

There is a report of a similar problem in this post. I am working on a fix and this should be available later today.

If you are able to view the MinimServer log, you can check whether the problem you are seeing is the same as the problem I am in the process of fixing. The problem I am fixing shows these messages in the log:

The is a fix for this NullPointerException error in MinimStreamer 2.1.2, just released. Please try this version to see if it solves the problem you are seeing.

My error log did show the NullPointerException error.
Just installed MinimStreamer 2.1.2 and tested. Everything is again working properly as before.
Thanks very much for the speedy resolution.
