OPC UA certificate error

Hello guys,

I am a beginner in node-red and trying to read data from OPCUA server via opc ua client node but I am getting an error of "invalid endpoint error: The connection may have been rejected by server".

As I try to activate this node by debug button suddenly my node red software stops working and there is a message of opcua certificate manager problem at the terminal.

Guys, I need some senior guidance, I will be thankful for any lead.

Kind regards,
Muhammad Rizwan Kamleen
