DNS IPv4 1.1.1.1 Problem

Hello,

i have problem with DNS IPv4 1.1.1.1/1.0.0.1. Now some sites aren’t loading for me - Zalando (clothing eshop store), AMD websites, etc. Custom DNS servers i using 2 years and it was never a problem.

After turning off the manual and aplly automatic settings DNS IPv4 websites they work. Is it possible that this is only a temporary problem?

Thank you!
