Cannot reconnect automatically after an Internet connection loss. RTMP error message

[DeineMATRIX]

When I have an Internet disconnection, OBS tries to reconnect automatically but aborts with an error message. There are problems with the RTMP key.

When I press connect stream, OBS does nothing. I can then only close OBS and restart it. Then it works again to stream without me having changed anything.

I have had this problem for a few weeks with OBS Studio 30.2.3
and the 31 betas and also with the final OBS Studio 31.0.0.

I have not changed anything in the stream settings for years.
I use Restream.io RMTP.

Error:
13:35:41.525: [rtmp stream: 'adv_stream'] Connecting to RTMP URL rtmp://live.restream.io/...

Yesterday I got a new stream key from Restream. I then entered it in OBS, closed OBS and restarted it.
Today still the same problem:

Internet provider disconnected for 24 hours. OBS tries to reconnect but gives an error message: Problem with stream key, please check...

I have had this problem for a long time. I can only restart the stream if I stop and restart OBS. Without doing anything to the stream key.

I don't see why OBS has this problem with me.

Than you for help
