Was this a fresh install or an upgrade?

Can you try it with a recent nightly? I’m not able to reproduce this on the recent build.

Is this a UA connection to another server or is it the “loopback” connection to the local Ignition OPC UA server? Can you upload the logs here or send them to support?

The server is the Loopback, with Ignition OPC UA, I have one more server UA using a kepware, but I couldn’t configure using the encryption, need to keep without encryption, because the certificate show at Kepware, don’t correspond with server, so the connection not work.

The log has more than 100mb, so I upload at OneDrive:
