Too many requests with too long a timeout.

[X3hf021]

Hello, we recently had the problem that there was a large amount of requests that blocked our ports.
The timeout was probably 30 seconds, and we opened more requests to Azure Server than available ports.

Is it possible that a large number of requests were not considered and thus there may be problems in the event of a server failure if the requests are not accepted by the Azure Server?

Can this still be adjusted so that only a maximum number of requests are opened simultaneously to avoid overloading the local server?
Thank you!
