[squid-users] SQUID PROXY ERRORS - SUPPORT

[Alessio Ballarini (External)]

Hi Squid Support,
we are facing a problem with Squid proxy, configurated on our server named
"amiproxy".

I explain the role of this proxy in the infrastructure as follow:

- There are two SAP application server that need to use a Proxy to reach a
remote server out of our local network.
- The Proxy is configured on "amiproxy" by using Squid (I attach the
squid.conf)
- The TCP connections work inconsistently: sometimes they work (200) and
sometimes they do not (503).

Specifically in the access.log of the Squid we registered these 503 erros:

1680672739.134 59768 172.29.7.148 NONE/503 0 CONNECT 195.75.144.10:22 -
HIER_NONE/- -
1680681044.960 60450 172.29.7.148 NONE/503 0 CONNECT
appbpe.pellegrinicard.it:443 - HIER_NONE/- -

We tried to debug the log of the squid, and we found that this error is a
"generic" application error that could depend on several factors.

I hope you can support us, because we are pretty sure that the cause
depends on Squid, since we tried to bypass it using a direct TCP flow to
the remote server from the SAP application server and we did not detect any
errors.

Thank you
Kind regards

Alessio
