Bug Report: outgoing API requests from fly Europe to Cloudflare

For a new days I noticed something weird; some outgoing HTTP requests from my fly app deployed in the fra region always time out, causing the app to 502. After a bit of debugging I found out that this affects outgoing requests to third-party APIs delivered through Cloudflare. Then I moved my app to another region (in the US) and now everything works - but of course eventually I want my app to run locally. Can you check whether there’s any traffic issues between your fra region and the Cloudflare CDN (probably also located in fra)?

FYI Cloudflare has a couple of locations around France:

Did the failing request always targeted Cloudflare?

We’re going to test this a little bit. There might be network issues between our datacenter and theirs.
