eBlocker will not receive a IP-Adress from the Fritzbox

Hello, I am using the white cube with a static ip-adresse. 

For another network I tried to changed this to DHCP but the eBlocker doesn't get an IP-adress from the fritzbox.It has a 169 ip adress. I can change it to a static ip-adress but why don't get  the white cube a, ip-adress via DHCP?

(The cupe was updated via the internet).

a xecond question: the eBlocker works with Windows 11 and it blocks ad from  kleinanzeigen very well.

When I changed the SSD with Debian 13 on the the same PC the not all the ads can't be removed from kleinanzeigen.

Thats is a weird behaviour??

Any ideas? Thanks
