@naga , thanks for the post!

Can you provide some additional details?  What kind of agent is this?  What kind of operation?

I found some incidents with this error for Hyper-V backups.  In these cases, the issues were on the Hyper-V end (and the customers engaged Microsoft support to fix).

Thanks!

@Mike Struening  thanks for the reply!!

This is Hyper-V backup job error we faced.

we checked the job manager logs and found network issue.

I attached the error details

That’s it!  Were you able to resolve the issue on the network end?

Thanks!
