Hi,
one more thing to try: switch off the console for a while (to let it cool down),
switch it back on and see if you can now connect. If yes then it may be a
temperature-related issue like one or more fans stopped on top of the AQS
cardcage (worthwhile checking if yours already shows the running state of
AQS fans under ha - DRU-managed devices - card cage. Power supplies or other
boards may overheat as a consequence and result in undesired behavior…
Good luck hunting,
Bert
