Google Play can't download or update apps via OpenWrt router

Hi, I have problem.

I can't download or update apps via google play on every device I have at my home, I am only getting loop shown on picture. Internet works in home, only Google play doesn't.
It works fine via 4G.

I tried using my ISP dns instead of Cloudflare, it didn't solved issue.
My network topology

Huawei ONT
| PPPoE on VLAN 35
GL-B1300 with OpenWRT 21.02.1 -> Galaxy S9
| 802.11r on 5GHz
Archer C7 v2 with OpenWRT 21.02.1 -> Galaxy S10

Any help is appreciated

are you sure your phone's using your DNSes ?

There's no guarantee, just because it's using your wifi.

I am 100% sure phone is using router DNS.

in that case, see what DNS names it requests ...

you're not using any DNS adblocker, by any chance ?

I can say the Google play installation wheel spins for me too, for a good 10+ sec,
before it actually starts the DL and install of the app.

I'm not using DNS adblocker.

Saw similar reports in IRC, a tcpdump would be helpful


Password: OpenWRT

EDIT: I forgot to mention, I am using software offload.

Some IPv6 packets are dropped when software flow offloading is used: FS#3373
As a workaround, do not activate software flow offloading, it is deactivate by default.

disable software flow and try again.

I am not using IPv6 on WAN.
