MSExchange 2010 EdgeSync fail credentials are invalid Event ID 1024

Been trying to resolve this issue for a bit, not really finding any absolute answers.  
"Failed to connect to the Edge Transport server ADAM instance with exception The supplied credential is invalid.. "
Another event indicates 1/3/2018 was the last successful synchronization and now I get "EdgeSync failed to confirm the credentials for replication account cn=ESRA<yada yada yada......."
I have searched hi and low for a way to fix this, without deleting and recreating a new edge subscription for fear of messing up the mail system.
This has been running fine for years, all the ports between the edge subscription server and the hub/mailbox server are good.  
I'd like to know how to fix the credential issue, hopefully step by step.   The ESM on the hub server shows the edge subscription is valid

Thanks in advance

I had a similar error in one Edge servere. I checked all DNS, ports,... but finally i recreated the edge subscription to solve the issue.
