Hi. Anyone know how to fix following issue? Error: cannot locate certificate file /opt/plcnext/appshome/data/60002172000051/lib/node_modules/node-red-contrib-opcua/node_modules/node-opcua-client/certificates/client_selfsigned_cert_1024.pem I have generated new certificates by using following command: openssl req -newkey rsa:1024 -nodes -keyout private_key.pem -x509 -out client_selfsigned_cert_1024.pem Where do i find the generated certificates on the PLCNext controller? Tommy
Hello Tommy, the files should be generated at the location where you called the command. I am not involved in the project but my first try would be to move the client_selfsigned_cert_1024.pem to the location the error message is pointing out. Moving the public key: mv client_selfsigned_cert_1024.pem /opt/plcnext/appshome/data/60002172000051/lib/node_modules/node-red-contrib-opcua/node_modules/node-opcua-client/certificates/client_selfsigned_cert_1024.pem Moving the private key (would probably be the next issue): mv client_selfsigned_cert_1024.pem /opt/plcnext/appshome/data/60002172000051/lib/node_modules/node-red-contrib-opcua/node_modules/node-opcua-client/certificates/PKI/own/private/private_key.pem - Marcel
