I/O error on POST request for "https://api.fitbit.com/oauth2/token"

[ismail-koembe]

Randomly I get errors for https://api.fitbit.com/oauth2/token call. 
Here is my cURL:

curl --location --request POST 'https://api.fitbit.com/oauth2/token' \

--header 'Authorization: Basic <REDACTED>' \

--header 'Content-Type: application/x-www-form-urlencoded' \

--header 'Cookie: JSESSIONID=1970EDD2F5A921D4600ED56818D89ECB.fitbit1; fct=bc3e2f3cefd34286920ed521cdfb75c9' \

--data-urlencode 'grant_type=authorization_code' \

--data-urlencode 'clientId=22CXWP' \

--data-urlencode 'redirect_uri=https://<REDACTED>' \

--data-urlencode 'code=985bff2c5f6608e4715205ac5fc1f4df26a297cd'

This cURL %90 works fine but sometimes I get an error at the first connection attempt. 

Thanks in advance

Hi @ismail-koembe 

We did have a slight problems with the /oauth2/token endpoint earlier this week that seems to be resolved.   Would you please let me know if you are still seeing the behavior?   If so, what error message are you getting?

Hey @Gordon-C 
I could reproduce the same issue last week and just 3 mins ago. The interesting thing is it happens at the first attempt.
[curl -X POST \\n-H 'Authorization: Basic <REDACTED>' -H 'Content-Type: application/x-www-form-urlencoded' \\n -d '"grant_type=authorization_code&clientId=22CXWP&redirect_uri=https://<REDACTED>/account/connect/fitbit&code=3c7475ac2da92e28383f3a9d22f1d3c85988369e"' \\n'https://api.fitbit.com/oauth2/token']" 

Next time same cURL with the new code worked fine (new code: 8d91230f3fa1f2a4a2917b5549be9ced241b1174) These codes are being produced on Fitbit and once we got it, we put them in our request. 
Since its reproducibility is very low, it is really hard to debug it.  

The error message :

Hi @ismail-koembe 

Are you still receiving the Connection Reset error on /oauth2/token endpoint?   

Thanks!
