Hi,

I have an issue with Node Red not loading back up after a reboot when using the OPC UA Contrib node. It stalls loading the Nodes. If i remove the node via NPM in CLI it just kills it all together.

Any help would be much appreciated.

Thanks

Symon

@bceyresy If you want help with an issue I suggest you provide details so people can help you.

1. What device and os are you running NR on?
2. What version of NR and node-js are you using (see the startup log)
3. What is the full name of the node at issue (i.e. node-red-contrib-?????)
4. Provide a copy of the startup log
5. are you using Docker and/or Home Assistant

Make it easy for people to help you otherwise they may just pass over your issue after all we are all just volunteers.

Thank you for the replay @zenofmud .

1. The device was using s Brainboxes BB-400 Industrial Edge controller.  
[https://www.brainboxes.com/product/industrial-edge-controller/bb-400](https://www.brainboxes.com/product/industrial-edge-controller/bb-400)

2. Node Red version was 3.x then we updated to latest 4x version and still the same.

3. Th node used was the - node-red-contrib-opcua

4. I will need to recreate the fault again as we flashed the device and used another OPC US node. I did take one screen shot attached here.

5.

We are not using docker or home assistant. However i did spin up a docker and had some bizare similar issue where once i put the nodes onto the flow, I deployed with them disconnected then lost connection to the interface & had to reboot docker container.

It could be hardware related or Node Red related. If the image attached could help point in a direction that would be helpful, i will recreate the fault and post back later on.  
Thanks

Symon
