problem with restoring database and configuring auto seeding in an availability group (SQL Server Always ON)

Hi. In my workplace, we have avamar server (software ver. 19.3) that is connected to data domain and we are currently facing a problem when restoring a database in an "Always On" AG. Although it removes the database from the AG, and restores it on the primary successfully, it fails when trying to configure automatic seeding in the secondary replica. The error in the secondary reads as follows:

2025-10-30 15:31:55 avsql Info <12978>: Forwarding [update_fc_status] request to: 10.60.25.248

Any help to get me out of this situation is appreciated.😊
