  • Update check failed `"apps.graphene.org": No address associated with hostname`

I have been encountering the same issue with my Pixel 8 for the last couple of days. I think it has only started since it updated to an Android 15 build.

I'm not using multiple profiles, only the owner profile.

Private DNS is set to automatic. My firewall blocks outgoing DNS-over-TLS but offers itself as a local network resolver via DHCPv4 and IPv6 RA. DNS-over-HTTPS isn't blocked by the firewall, yet. I'm not certain what Android will resort to using under those conditions.

The update check has failed four times during the last 24 hours according to Notification history, but I think there were a few before that as well. It's certainly happening far more frequently than it has in the past. It may have happened occasionally before, but only as isolated occurrences that weren't worth remembering.

I'm using DuckDuckGo browser's App Tracking Protection, which sets up a fake VPN connection to filter outgoing traffic from the tracking & telemetry frameworks built into apps. I don't believe has caused any DNS-related issues before, but I'll try disabling it to see if that makes any difference.

I get the same error from time to time. Also on 5G, no VPN, no custom DNS.

However, it's not a big deal, because usually it works again and I get regular updates for Vanadium and the other GOS apps.

I believe it's the same for me. P8P, VPN, wi-fi, on owner profile. It's been happening for a while. I'm not informed enough to understand why that is.

Unable to resolve the server name.

java.net.UnknownHostException: Unable to resolve host "apps.grapheneos.org": No address associated with hostname

This has also been happening to me. I've received the error many times in the last 2 weeks or so and I don't remember ever seeing it before this, at least not this much.

Same here, I've seen this happen more often recently.

Perhaps a retry policy (e.g. 1 or 2 times after a 30 seconds delay) before showing this error message is in order?

    detective1 I have the same problem.

    The report is of a network error. Network errors can be caused by many factors. The "solved" marker that time was because of a cause that did not require any user action.

    If you got this message just once, probably ignore it. If it's happening a lot, there is probably some problem with some network. Finding and resolving the problem will require some detective work. For example, does it always happen when you are at home, or at work, or in between?

      It doesn't work permanently. I have now found the problem. It was because of the sim card I used. Now I just give my Google Pixel hotspot. I just hope that my iPhone, with which I give the hotspot, leaves no data/traides on the Google Pixel. Does anyone happen to know that? And thanks for the help!

      I have the same issue. Usually it worked the next day or so but by now this is frequent and my P8P is missing the last 3 updates (still on 20241212).

      No VPN. Tried WiFi, Mobile Data, default and automatic DNS. Nothing works. Anybody got a clue on this one? Also how to update manually? Amy risks in doing so?

        6r4f You need to fix your internet connection. It's not a GrapheneOS issue.
