Apologies first off - first timer here :/
I have faced the same issue as above, tried several versions unsuccessfully, now on 5.2. I have managed to get the NAS ( HP Gen8 Microserver , bare metal build) visible on the network and to the last stage - login.
At which point I get the header line???
This is my first login (and there was a password, no blanks etc.)
Any ideas, as I am now out of luck, worried it may be down to the mac address... but open to suggestions or if anyone knows how to fix.
Was so close, yet so far!
