Replication issue after node rekick start

Hi

i am having a big issue, with reliation setup again after node was re kick started.

i have HQ with a big avamar grid acting as the target of replication for many single nodes on remote sites.

one single node crashed and we did re-kick started the node and installed the same avamar version as before.

now we are trying to configure the replication again but we can not as the system says authentication failure, the replication was working before, and accessibility to target avamar is check.

i think the the HQ (target) remembers the node, can you hep in making the target forget about the old configuration for the node before we re-kick start, and setup the replication again.

both sre on version 7.1.1-145
