Dear all,

i used node-red-contrib-opcua-server. We use Compact server to perform a connection with a opc client.

The client that connects to my server us a certificate, but the server don't accepts the certificate & the connection don't be accepted by the client.

How i can accept the certificate that client send to opcua server?

Thanks

If does not look like the author is maintaining [that node](https://github.com/BiancoRoyal/node-red-contrib-opcua-server/issues/72).

You might want to try an alternative: [node-red-contrib-opcua-server-refresh (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-opcua-server-refresh). This one is updated and the Author is actively maintaining it. You can raise issues on the repositories issue tracker if needed.

Typically you search for the node (I provided the link above) then see if it has a link to the GitHub repository typically labelled "View on GitHub". From there, you check to see if the repository has an issue tracker (look for a tab labelled "issues". This is a section where you can raise issues and feature Requests etc. You'll need a GitHub account to do this.
