fly machine cannot find upstash redis server

Earlier this day, our fly machines stopped recognizing upstash redis servers with the following
error:
IORedis Client Error: DNSException:
[info] syscall: “getaddrinfo”,
[info] errno: 4,
[info] code: “ENOTFOUND”

We’re running this on Bun at GRU region.

That’s a strange behaviour as we are able to connect to the redis server by using fly redis proxy and changing our .env config to use the proxy URL. So, the same method with the same redis instance is able to run normally.

Is there any issue related to this happening with anyone else?

Can you spin up a fresh machine in GRU and contact Upstash from there? How about a nearby region?
