Trying to connect an Elixir app to a provided Redis URL from upstash.io . But I get an :nxdomain error when I try to deploy (and connect to it). Any ideas, maybe missing config in the fly.toml?

Found it here: [image] [SOLVED] Elixir/Phoenix -> Redis Instance - Unknown Host Questions / Help Hmm. Strange. First thing: [experimental] private_network=true … is no longer needed. That’s confirmed by Fly e.g Hence that makes no difference. So yep, you can remove…

The Redis URL resolves to an internal IPv6 address, so your app and Redis client need to be configured to support that. Check our this thread for more info: nxdomain for Elixir app

Great! Was the problem that Redis was deployed in a different organization?

No, they were in the same org. But somehow having two regions allowed the second deploy to connect and the canary to pass and roll it.

Upstash prodived Redis URL not reachable from buildpack?
