Installed libretime (github stable date 20 mar 2023) (on ubuntu 20.04 server) and it worked, scheduled a show, it went on-air, and also streamed into it via mixxx.

But after a few day, i am not able to get any show ‘on-air’.

The status in the GUI report that every ‘service’ is okay.

Any idea?

the liquidsoap.log:

```auto

```

the playout log:

The bug has been fixed already.

~~But if you are not sure of what you are doing, please do not run LibreTime from the main branch, as it might break. Checkout a tagged version.~~

EDIT: Oh my bad, the patch was only merged in the main branch, not the stable branch.

Thank you,

i have updated via the stable branch,  
and libretime is back on-air again.  
Problem is gone.
