Hi Community

I have a brand-new DMA running on Win11 laptop as a demo. It was initially installed as version 10.2 and worked. Following upgrade to 10.3, and beyond the Cube client updating itself on the first attempt to connect, I can no longer connect via DM Cube application either locally or remotely.

Message in Cube GUI is:

"Connection timeout. The DataMiner agent did not respond in time."

Cube log reads as follows (captures several login attempts):

Any advice as to how to further diagnose or rectify this issue would be much appreciated, please.
