I have installed Lineage OS 16 (android pie) for my oneplus one (although this issue existed in android Oreo as well).
I am having a very interesting/weird issue with my phone that might be related to DNS.
When I open chrome when on mobile data, most of the time (7 out of 10 or so), an error pops up almost immediately (within 2 seconds of pressing go to page) with the message:
To test my DNS theory, I download a DNS changer app. These apps work by making a local VPN and this gives them the ability to override their DNS settings.
After doing this, my mobile network works flawlessly.
Is there any way to fix this natively without resorting to hacks?
