EA App Game Library empty because of AdGuard/PiHole DNS

 I installed the EA App and my Library was empty.

Google said I should empty the Cache, Temp Files and kill the EA Background Service but that didn't help at all, ending the Service just ends the App Process as well.

I'm using Adguard Home in my network, a PiHole alternative and I figured out, that's the issue.

2 Domains need to be whitelistet to work:

sdk.split.io

js-agent.newrelic.com

So I needed to open my servers Adguard Webinterface->Filters->Custom Filter Rules

add the lines:

@@||sdk.split.io^$important
@@||js-agent.newrelic.com^$important
