What exactly is the problem?

Are you worried about the logs saying that your AutoEverything is failing to change the channels or the Ethernet Link down that happened on the 26th of December?

I’m not seeing a major issue here. The AutoEverything message is from the unit not being able to communicate the cloud.

Hello again ,when the c5c doing this ; connection is lost for 1 minute and then connected. But there is no link down / link up seeing at log. :confused:

Yesterday i closed the cloud connection. There is no problem for today. I am checking the log everytime.

Hi,
NMS CHANNEL_HISTORY TRANSFER FAILED is harmless error message printed in logs. This is what was told to me by Mimosa Support. You may want to upgrade to 2.5.2 version, which most likely solved the issue.
