Your network has problem. Check whether your microG Companion has network permission and your network environment.

I was in a network with an AdGuard instance and tried moving out of it. I still get the same results.

If you're getting the same error it means that something with your DNS resolution is not working.

Either an on-device firewall or content-blocker, network permission as @CoelacanthusHex mentioned, or your network or ISP has something wrong with DNS or is blocking that host for some reason.

I assume internet on the device is otherwise working?

Here is the DNS info for that host:

host play-fe.googleapis.com play-fe.googleapis.com has address 142.250.68.14 play-fe.googleapis.com has IPv6 address 2607:f8b0:4007:80f::200e

You can try opening a terminal window on the device and typing this to see if it's not just a DNS error (you may need a root shell for this to work):

ping 142.250.68.14

If it's able to contact that host (not using DNS name), then you will see output like this scrolling down the window:

64 bytes from 142.250.68.14: icmp_seq=3 ttl=53 time=40.716 ms ...
