Few of my teams webhook requests are failing

Question

Hello,

I am working with Microsoft teams webhook. most of the request that I am sending from my end are getting successful and are visible in my teams channel.

But randomly few of them are failing with this error.

Failed to post data in teams webhook <my_webhook>. Error: HTTPSConnectionPool(host= <my_host>, port=<my_port>): Read timed out. (read timeout=300).

I tried increasing the read timeout to 500, still facing the same issue.

Not sure why this is happening.

Would appreciate your help.

Thanks.
