It seems like AVM FRTIZ!Box routers don't trust the root certificate "SSL.com Root Certification Authority ECC" (0x75e6dfcbc1685ba8).
It's only possible to use dot.sb if the certificate check is switched off.
I already contacted AVM and they replied
I have just forwarded your request to our product management as a suggestion for improvement, so that the root certificate you mentioned will be implemented in an upcoming update.
Just wanted to let you know, that dot.sb can't currently be used with FRITZ!Box routers if the certificate check isn't switched off.
