well, thats a first. I’m constantly getting an ERR_NAME_NOT_RESOLVED error on all devices connected to my local network. I’ve been battling these DNS issues for two days now, only to realize my Heroku deployed rails app is unreachable ONLY from my local network (WiFi). when trying to access it through the cellular network - everything works as expected.
Configuring Cloudflare DNSResolver / Google Public DNS seems to resolve ( ) the issue, but as I’m not entirely able to understand what causes the problem (absolutely not a DNS expert), I’d like to know if there’s a way to prevent this problematic behavior for other visitors.
Thanks in advance
