Facing issue with concurrent requests

[PiyushJainn]

Observed the hrequests have an issue with concurrent hits, if I hit same requests with 2 processes and 10 threads each process it is giving the below error. But with 1 request at a time, it is working.

hrequests.exceptions.ClientException: failed to do request: Post "<website_url>": net/http: request canceled (Client.Timeout exceeded while awaiting headers)

Can anyone tell me is this website rate limiting issue or issue with the hrequests library
