Node Red Crashes when subscribed OPCUA Server goes offline

[skroll2610]

Hi, I have a problem with plugin version 0.2.337 and node red 4.0.5.

I suspect the node red server crashes when the host where the OPCUA server is running on, is shutting down.
I was running an old NR version (2.x) with a really old plugin version (cant remember) where i didnt have this error. since an update, its failing on multiple Node Red instances on different machines. (I also tried another server, same result).

The data and configurations have not changed since 2020. so I would assume that this is not the problem.

Do you have a solution?

Kind regards

Sebastian

@mikakaraila .. I recently updated OPC UA node then I was getting this information in console...

"connection break"... + OPC UA IP

is this normal? or Is it my network problem?
