connection aborted when --no-keepalive

[balait4]

Hi All,

Kong version: 3.4.2
KongIngress: 2.12.0
- We have the same issue as here: #9441,
not sure if its just urrlib3 or urlslib3 in combination with our Kong, the connection is not kept alive and aborting after 180s
- I was able to replicate it with the customers request with curl (connection aborted when --no-keepalive and working otherwise),
and with python (with error after 180s: requests.exceptions.ConnectionError: ('Connection aborted.', OSError("(104, 'ECONNRESET')")))
- I tested the workaround for python (psf/requests#4937 (comment)) and it worked for me: got response after 9min (routing cached)
