Eduroam and other networks not working

Hello,

I tried this dns for a couple of days and I blocked a couple of domains, howerver i decided i didn't want it anymore because eduroam didn't work with it. After discovering this i deleted my account, but now however i can't acces those sites on hy home network nor anything on eduroam. I'm not sure what to do as i've tried a whole lot of things and can't figure anything out. The problem is only on my phone and laptop and not with other devices. If i can't resolve this im not able to use my devices anymore. Please help!!
