I am using Selenium Server version 4.31.0
I have a Selenium Grid running on three RHEL9 servers. One server is a hub, and the other two are nodes.
I have a Selenium Grid running on three RHEL9 servers. One server is a hub, and the other two are nodes.
The grid starts and works as expected, seeing both nodes register with the hub.I have since added a TLS certificate to the hub. The certificate is self-signed using a corporate CA. I am able to access the hub using HTTPS with a browser without issue.
I have verified that the corporate CA intermediate and root certificates are on all of the servers and in the Java certificate store. Using a simple Java application I am able to connect to the hub from the node server without any certificate errors.Ever since I added the TLS certificate, the nodes no longer register with the hub. The final message in the node’s log files is, “Registration event failed after period of 120 seconds. Node will not attempt to register again.”
There are no other errors in the log.Are there any suggestions or other troubleshooting I can do for using TLS with Selenium? I am out of ideas of what it could be.
