Please try setting up a new connection to the PLC in UaExpert, not using the „Recently Used“ link.
If that doesn’t work, please check that the OPC UA Server is enabled on the PLC using the Web-Based Management page.
I just tried upgrading UaExpert to the latest version (1.6.2) and it connected OK to my PLC.
it’s still not stable, this afternoon I accidentally connected, then again like the clip below, very annoying, I will update to the latest firmware to try.

Are there any clues in the Output.log file?
Can you please try a different security algorithm. the latest firmware, with an upgrade of OpenSSL, has disabled some of the less secure algorithms. In UaExpert I do not see „None“ with the latest firmware.

Thanks for your help, I update the firmware for PLCnext to the latest version 2022.0.4 LTS, extremely stable
