It sounds like you've encountered an issue with concurrent request limits. This typically happens when you've reached the maximum number of simultaneous calls that your current plan allows. To resolve this, you can either upgrade your plan to increase the concurrency limit or wait until some of the current calls are completed before initiating new ones.
If you're seeing calls in the queue that are not being connected, it could be related to the same concurrency issue. The system might be unable to process new calls because it's already handling the maximum number.
If you need further assistance or if you believe this is an error, please reach out to support for more detailed help on managing your concurrency settings and understanding your current plan's limitations.
