A few days ago my Google Pixel 6 Pro suddenly started causing problems:
When navigating to websites with my mobile connection I would receive the error message "ERR_NAME_NOT_RESOLVED".
This happens only via my mobile connection, WiFi works fine.
More details:
- I'm currently in a foreign country using data roaming
- the phone worked just fine until two or three days ago.
- I cannot pinpoint if there was any specific change that caused the weird new behaviour
Some other weird observations/solution attempts from my side:
- my private DNS settings seem to get ignored. I had it set to the mullvad DNS, and changed it to the cloud flare address one.one.one.one during troubleshooting. Net analyzer however tells me that the WiFi connection uses the DNS server IP 79.79.79.79, while my cell connection uses the DNS server IP 62.109.121.17
This seems to be the likeliest culprit, but I have no idea how to actually fix this. - I checked that my VPN was turned off/not accidentally killing the connection with a kill switch
- I checked chrome://net-internals/?#dns in vanadium and pressed clear host cache. Using the domain lookup field returns "An error occurred while resolving "Reddit.com" (net::ERR_NAME_NOT_RESOLVED" even on WiFi connection, but connecting to the site while on WiFi does work.
- I restarted my device, no changes
- I installed all the latest updates, no changes
- I reset my network preferences via settings > system > reset network preferences & restarted, no changes
- I set the private DNS setting to off & automatic, no changes in both situations
- I installed a second browser (Firefox) to confirm the problem also appears in that browser.
I've tried everything that I could think off, and now I'm all out of ideas. Any suggestions would be appreciated.
