python: requests.exceptions.Timeout vs requests.models.Response.status_code 504 ( gateway timeout )

Question

requests.exceptions.Timeout VS requests.models.Response.status_code = 504 [gateway timeout]

what is the actual difference between the two as both deals with saying timeout has occurred?

Let us say Service s1 makes call to S2

In s1:

request.post( url=s2,..., timeout=60 )

when will requests.exceptions.Timeout be raised and in what scenario 504 is received.

Can retries be made for all of those exceptions - I believe answer for above question might give lead to this..

Thanks in advance.

Answer 1

The gateway timeout means the connected server had some sort of timeout after receiving your request(ie you did make a connection). However, the requests timeout exception means your script never connected to the server and timed out waiting on a response from the server (ie you did not make a connection).
