Cannot see most of the internet

Hi,

I can visit some websites (wikipedia for example) but cannot see most of the internet.

ERR_NAME_NOT_RESOLVED

Why could that be? What can i do?

Warm regards

have you changed anything in DNS setup ? Private DNS or any adds or tracker blocker like blokada, TrackerControl running ??

I hope, I did not. Just started.
“Use network DNS” is green…

The problem happens only if I use mobile data.
In that case most websites dont work and I cannot use Signal either.
Everything works fine via WLAN …

Ok, than check your APN in mobil Network settings

sounds like my provider …

I mean: similar name as my providers name.

apn seems to be all right. or what do you mean by check?

Check the settings in apn with them from provider. Most provider a shown the apn settings on there webpage
