[pve-devel] [PATCH widget-toolkit v2] window: ACMEDomains: show error dialog on domain limit

[Christoph Heiss <c.heiss@proxmox.com>]

Currently, this just fails silently for users and only logs an error to
the console. Improve the error message & show an alert dialog on
failure.

This affects both PMG & PBS, as they use the exact same codepath/panel.
