Configure NOAH 2000 - Always resets to mqtt.growatt.com

[Baymax2909]

Hi!

I installed an mqtt-Server, added GroBro and set up everything with certificates.
I was able to add both of my NEO 800-MX inverters and in addition I blocked both from accessing the internet.

When I try to add my stacked NOAH 2000 I face some issues. Despite I was able to reconfigure the NOAH 2000 (delete in ShineApp and add it again) and add my domain/port in the settings, the NOAH 2000 does not connect to my custom mqtt server.
It always connects to mqtt.growatt.com instead. When I try to block internet for the NOAH 2000 and start the configuration then I get an error message that it could not be configured.

Any ideas what I could do better can help me :)

Softwareversion of NOAH 2000: 15.10.07.4017

Can you post your broker log, please?

I do not need to. This morning it connected to my mqtt server.
Not sure what happened… it seams like it needed some time ;)

there is nothing inside the logs. It is a normal first connection.
