Several Websites unreachable systemwide in WLAN connection

mitjas

I'm experiencing "Adress unreachable" notes on several websites (not all) since a few weeks ago when connected to my home network. Before that all went well on my pixel 6
The problem

is systemwide (does appear in all browsers, no matter if based on Chromium or firefox)
is reproducable on two different GrapheneOs devices (Pixel 6 and 7a)
interrupts Tor-browser-connection
doesn't appear during mobile network connection
doesn't appear on other devices connected to my home network (no matter if Linux, Windows or Android devices)
persists after resetting network data on GrapheneOs devices and my homenetwork device

There are no changes to the standard graphene settings (especially no custom DNS or VPN is used)

Any ideas where to look next? Anyone else who suffers that problem?

Thanks and best regards!

mitjas Any ideas where to look next?

In theory there might be some subtle disagreement between DNS data for those domains and the GrapheneOS resolver code.

If you were to indicate which domains, people could try to reproduce the issue.

Are you using any filtering on your home network like a pi hole ?

Thanks for your answer! Interestingly the Problem suddendly disappeared a few days after my first post.

If the issue will return i'll post it.

mitjas Thanks for reporting back. It's possible that troublesome DNS records aged out of a cache.
