OPCUA client error

Hi all,
I'm working with a opcua server/client architecture in my nore-red app.
At every deployment/restart I have 3 different errors, related to "client secure channel layer" as detailed in attached image.
Being a novice with both node-red and opcua, I cannot understand what the reason is.
Can anyone help me?
Thank you

As the terms "keepAliveManger" and "client secure channel layer" dont show up on the forum, I would suggest you have a read through the nodes existing issues - see if anyone has had this and solved it.

If not, then raise an issue on the repo - include information like the nodejs version, the node-red version etc.

Also, please feedback your findings to the forum for future readers.
