0.17 fails to connect to kopia server through ansible

[pdarko2]

when connecting to kopia server through ansible playbook, on one server it fails with following in cli-logs log file:

Connecting 0.17 from command line works; connecting 0.17 from all other servers works. Reverting to kopia 0.16.1, connecting works. URL obviously has address and port, but error line reports them none/missing.

@pdarko2 is the server address IPv6 by any chance?

[pdarko2]

No, name resolves to ipv4, and servers use ipv4 only.

[pdarko2]

also, using ansible.builtin.raw instead command/shell seems to work, so it's some specific way ansible calls kopia throgh it's command/shell module.
