Debian Buster and Raspbian apt update cannot resolve servers anymore since 1.5 months, very slow till no updates

Hi!
since 1.5 months my internet connection makes problems and i changed a lot of things, .e.g. i changed my public IP to private in order to counteract DNS spoofing and DoS attacks. I changed from the Google DNS servers to my ISP servers DNS servers. Finally, i changed to a new internet fee from my provider from a 30MBit/10MBit LTE line to a 100MBit/20MBit LTE line. Things improved greatly but the only problem i have still is, that my apt update seems to not work anymore at all. Can it be that my ISPs DNS servers are spoiled in relation to Google DNS servers for resolving the linux apt servers? What else could be the reason for this problem?
