fssantos95 commented 3 years ago

Hello Mika,

Today after the update to 0.2.91 i have been geting these certificates errors: image

Befora that i just created a client and it was all good. My OPC server has no credentials. Can you help?

fssantos95 commented 3 years ago

Already tried to delete certificates so that they regenerate but no success.

This requires a bit more, node-opcua and node-opcua-pki contains config.js that is used with command to create certificate. openssl needs many parameters and they must be correct and run in certain folder.

I will look requirements to create certificate for the client...

Found: https://stackoverflow.com/questions/50328537/generate-certificate-for-opc-client

And read from the end, use your real IP address.

But where do i get all those parametrs? Is there a reason why the node-red OPC certificate stopped working? I already uninstaled everything and still get the same error.....

Check first certificate folder exists: c:/Users/admin.exporplas/.node-red/node_modules/node-opcua-client/certificates

Then there should be certificate file: client_selfsigned_cert_2048.pem

Please report your findings.

There is breaking change in node-opcua v2.29.0 (downgrade to node-opcua v2.28.3 for a while).

OPCUAClient & OPCUAServer : the location of the default PKI is now created in .config folder or in the %APPDATA% folder instead of inside the node_module itself.

I didn't have that folder Mika.

I downgraded node-red-contrib-opcua to v0.2.89 and node-opcua to v2.82.3 and all is working again. Should i wait to update?

mikakaraila commented 3 years ago

I need couple of days to make migration, but you can install manually older node-opcua v2.28.3

mikakaraila commented 3 years ago

I made new version 0.2.93 that uses node-opcua v2.28.3 I need more time to do all changes.

Ty Mika!

Latest version is now v0.2.94 but it uses also new node-opcua that uses certificate manager for client. There are some topics (issues) on node-opcua so I expect I have to update node-opcua later.
