Hi Dirk,

Sorry for my late reply! On some day of the second last week, the reestablish network connection problem didn't exist while I hadn't done anything to RevPi Core3. I want to simulate the error again for a long time, but not realized.
Maybe the issue can be closed. Thank you!

Hi Dirk,

I have read that link. Then I try removing the node--"node-red-contrib-revpi-nodes" and the problem is gone.

Hi Dirk,

Sure the command is entered on RevPi!
After the error is reproduced, I call ethtool and the result is "Link deteted: yes", "Auto-negotiation: on".
