Hello *,
I think we/I completely forgot about this patch. Sorry.

Hello Stefan,
first: Thank you for developing this fix. :-)
In case a GeoIP related firewall rule should be created, the script now will check if the given location is still available.
Fixes #12054.
Thanks again - however, there is one question left (see below).

Since I have no idea how to avoid this, there are no subjective objections (!) against the patch from my point of view. It would, however, be better if this situation never happens - as described in #12054 ("A1/A2/AP/EU" currently not working/not present).
I think this is a valid objection, although I think that the code here should be merged as is.
Yes...

In addition there should be a patch to the UI that fixes what Peter has raised.
