USG FLEX 200H -1.30 (ABWV.1) - Port 3 is down

HUBERT_KASPRZAK

• For two days at a similar time, Port 3 has been turned off. The only solution is to remove the cable and turn it on again. This is not a cable problem.

Can you add another port then use that to see if the same thing happens with that port?

Further diagnosis of the problem on January 1-2, 2025. The system turns Port 3 off and on by itself.
