Connection Reset error for POST request to "https://api.fitbit.com/oauth2/token"

[wakanda]

Hi,
I am having trouble with the Fitbit API when making POST requests to the "https://api.fitbit.com/oauth2/token " endpoint. Out of 33 recent requests, only 16 were successful, and the remaining 17 resulted in a "java.net.SocketException: Connection reset" error. This issue could be related to network connectivity or server-side/API problems.

The requests with errors return in about 50 milliseconds, which makes me think they might not be reaching the Fitbit server. I kindly ask if it's possible to access any logs of the requests I sent. These logs would help me understand if the problematic requests are reaching your server and offer more information about the issue.

I would appreciate any help or suggestions to fix this problem. Please let me know if you need more information or details about my application and network setup.

Thank you for your attention and support.

Here is a more detailed error log:

Hi @wakanda 

I will need to collect some information from you to look in our logs.   I will send you an email with the information that I need.
