Garmin Connect no longer works - problem with connectapi.garmin.com

Garmin Connect no longer works for me on Google Pixel 6a: my Venu 3 is not syncing, and when opening Garmin Connect it basically says "An error has occured" everywhere. In the device sync log, I can see:

Any ideas?

  • The API service self is up and all right, according to Garmin Connect | Status. Try an alternative Internet connection (on the phone), if you can (i.e. mobile vs Wi-Fi, or a different Wi-Fi access point). Sometimes your IP address may get blocked by CloudFlare, resulting in connection refusals, and the block may take a few hours (up to 24) to resolve. Or sync over the USB cable to a computer with Garmin Express.

  • Thanks. However, the sync fails both with my home Wifi as well as mobile cellular network. Also, the problem has lasted since monday, thus a lot longer than 27 hours. I have also tried clearing the Garmin Connect App cache. 

  • Try it with another phone, or as I wrote with Garmin Express on a computer. Also try accessing the URL https://connectapi.garmin.com/upload-service/upload with a browser, and see whether you get an JSON answer or rather an HTTP error. The JSON response would return the following error too (since the request does not contain the required variables), but at least it will tell you whether the servers are accessible from your device. If not, then there might be a local networking problem, or a more serious block by CloudFlare. You could also try contacting the Support and see whether they can help better.

  • I get:

    {"clientMessage":"Reference Error ID in error logs for further information","errorId":"acf37c85-124e-409a-913e-ca9ff91e8e56","error":"NotAllowedException"}
  • I get that too, and I do not have any problems with syncing. So at least the connection to the server seems to be working normally.
