Hi Joel,
Try adding -D flag to doveadm, this is the debug flag.
Cheers

Hello all,
I'm trying to use deoveadm to sync from a dovecot server running version 2.3.21.1 to a version running 2.4.1. On the side initiating the "doveadm sync", I get the following error:

Neither server has errors in the log corresponding to this error. Both servers are still running after this error. I'm looking for some help in how to debug this. The above error is entire and only changed to obfuscate domain names and IP addresses.
