can't connect to online mode only with my home wifi

[Michal45]

so we have an adblock on this network, but iv'e tried to disable it and run \flushdns and them reopen steam, and that didn't help. when signing out and trying to sign back in i get e20 which means from what i gathered that connection to steam servers failed. also tried re-installing steam altogether. needless to say i do have internet using this wifi-network. please help!

If you think it's a DNS issue just point your computer to a DNS server that doesn't have that problem, like 1.1.1.1

You can static DNS independently of IPv4.
