I have 2 different base domains with two different networks I added the same nodes in both the networks For one network all the nodes are health, for other it's giving an error What's the probable root cause and how to mitigate this ?

the error indicates an mq connectivity problem. See MQ troubleshooting https://gist.github.com/mattkasun/face2a7c1f32031a2126ff7243caad12

Thanks, will look into it. Observation: If the peer is not shared by any other network, it is in HEALTHY state. There's no impact on it

I have observed the same thing when connecting the same nodes to two different mesh networks run by different Netmaker servers. Both networks work, but nodes on display as healthy on one or the other

Yes I'm also showing the same thing. That node is shared by two networks. One is in error state while the other network is healthy. It works on both networks, just the health state is having issues with one network. .
