Weird connectivity issue with telegram

1

Hi, big fan, hope you are all well.

I have a really weird issue with deployments.
I am running a telegram bot, which works fine locally (and on fly.io) if I do this:

Create app
deploy app (crashes, no secret)
add secret (works)

if I deploy a new version, the app crashes with:


/app/node_modules/telegraf/node_modules/node-fetch/lib/index.js:1505
                        reject(new FetchError(`request to ${request.url} failed, reason: ${err.message}`, 'system', err));
                               ^
  FetchError: request to https://api.telegram.org/[REDACTED]:[REDACTED]/getMe failed, reason: connect EHOSTUNREACH 2001:67c:4e8:f004::9:443
      at ClientRequest.<anonymous> (/app/node_modules/telegraf/node_modules/node-fetch/lib/index.js:1505:11)
      at ClientRequest.emit (node:events:513:28)
      at TLSSocket.socketErrorListener (node:_http_client:502:9)
      at TLSSocket.emit (node:events:513:28)
      at emitErrorNT (node:internal/streams/destroy:151:8)
      at emitErrorCloseNT (node:internal/streams/destroy:116:3)
      at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
    type: 'system',
    errno: 'EHOSTUNREACH',
    code: 'EHOSTUNREACH'
  }

This error occurs ONLY if the telegram API is unreachable, which leads me to believe there is a race condition somewhere where the instance doesn’t (yet?) have no connectivity?

To reiterate, if I: delete app, create app, deploy (fails due to missing secret), add secret
it works without a hiccup.

If I then deploy a new version (same exact code) it produces the error above.

Any hint on what might be happening here?

Thanks

Hi @0plus1

Thanks for reporting this.
It was a routing problem that affected a bunch of our hosts in syd. Should be fixed now.
