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.
