Skylla-i canbus problem?

I have two skylla-i chargers (24V/100A) connected via canbus and they are constantly throwing off two errors. Most of the errors are 65 which I gather means one of the skyllas has lost communications with the other. And less frequently I get error 67 indicating it has lost communications with the BMS. They are configured for canbus BMS control.

On the canbus are the two skyllas, two MG BMSes, an MG SmartLink, and an Octo GX. The skyllas are running firmware 2.07 which I think is the latest. It is NOT connected to N2K.

In the past this has worked OK, but now it throwing off these errors. I have a friend who has encountered the same errors in a similar config and was unable to find a solution.

I’m open to solutions, things to test, etc.

Thanks
