Any advice on what might be going on and a possible way to resolve would be greatly appreciated.

Have run SSH with -VVV option, though nothing stood out in the debug messages. If required I can post the output, let me know.

If there is a duplicate answer please just point me to that, I have not been able to find anything during searches ЁЯЩБ … Cheers.
