Linux sat server shows unknown location

Hello,

we have 10 sat servers, all on linux.

2 of them show unknown location, also if I assign the right location to  the server in the settings of the server. All other is working well.

The  2 servers are on SLES 15.2 and SLES15.1.

The working servers are on the same linux version.

We only check the IP range to determine the location.

Zac cc and zac ref general bypasscache will not help, also reboot of the server.

Any idea?
