Error "Keine Antwort vom Server" (No server response)

[Parkelch]

I would appreciate help in this case:
I've got 10+ meross devices: mss210, mss510, mss710. Node installed, key known and working.

Some of the devices are working without any trouble. Some do not react when triggered by "true" or "false" injection.
All devices are properly installed, have their IP-adresses and are all able to trigger by the meross app and have the newest firmware.

When triggering the mentioned mss210 and mss510, I get the message "Keine Antwort vom Server", meaning no server response.

I have no clou where to look at or what to do for a solution. Thanks for your help.
Parkelch.

@Parkelch I don't have such devices, so it might be difficult for me to help you. Nevertheless I would like you to first check if you're using correct IP addresses for devices you're getting errors from. Might there a firewall filter out some traffic?

@dehsgr Unfortunately is this not the problem. I checked with my FRITZ!Box all registered IP addresses. Made new nodes, changed some, but always the same devices are not switchable. At these nodes / switches no debug notes occur.
I'll check some other possbilities and come back to you. Thanks so far.

But all devices are on same firmware? Very strange then. 🤷🏼‍♂️🤔

@Parkelch are you sure error is coming from this node instead of node-red itself? I just recognized message in your screenshot seems to be from crashing/restarting node-red instance. Do you have some console output in time the message pops up?
