About deploy pve worker on the air-gapped envirment

Hi ​@nsofl.chen - no, Veeam doesn’t require internet access for worker installs. See below reference in teh Uesr Guide on Architecture for PVE & Veeam:

https://helpcenter.veeam.com/docs/vbr/userguide/pve_infrastructure_components.html?ver=13

There is a somewhat similar thread about Updater Service on v13.1 below:

Maybe reach out to Support, and monitor that post for resolution to see if what Support does helps your issue as well.

Best.

Thank you,

After reinstalling version 13.0.3.63, I’ve been using the backup LAN IP for everything without configuring any DNS A records or the hosts file. The worker installed and tested successfully, and backups are working normally.

I wonder if version 13.1.1.18 might have introduced some restrictions?

That's possible. Only Support would be able to answer that. 

Glad you at least got back to a working state. 

Hi ​@nsofl.chen! During the V13.1 beta the update servers weren’t available but the worker deployment proceeded after the update ran into a time out. I just tried it again in my lab with the latest build and the deployment succeeded. Could you post a screenshot of your error message or share the full message?

Hi ​@regnor 

This error occurs in version 13.1. I reinstalled version 13.0, and it worked fine, but after I updated to 13.1.0.411 or 118, the error reappeared.

This looks like a different issue than the Veeam Update Repositories not being reachable. Is there a firewall or proxy between the workers and the Veeam Backup & Replication Server?
