API Timeout Issue Starting on 05.09.2024

Since this morning, we've been encountering issues with API requests, with many of them timing out unexpectedly. After extensive testing and debugging, we found that the timeouts occur randomly, potentially due to a throttling limit or an API usage capacity per seconds or minutes.


Interestingly, when making the same API requests from different IPs or localhost, no timeouts occur. This leads us to believe the issue could be related to limits based on IP or domain.


This log is used to track when the timeouts occur. As you can see, the timeouts happen at random intervals—sometimes after the first request, other times after the second, fifth, and so on. There's no consistent pattern.

Earlier this morning, I checked the status of the billing EU service API and confirmed there was an issue. However, after some time, the issue was resolved, and the status returned to green.
