Hi Alex, Which log should those be found?
Can’t see “HTTP Server RESPONSE” in the access.log or cache.log. Regards, Ben.

Unfortunately, due to Squid logging bugs, ERR_READ_ERROR/WITH_SERVER does not always mean what it says. For example, parent Squid could have closed the child-parent connection prematurely, but there could be other reasons. A full debugging log should give us more information. > 2024/07/12 14:57:08.678 kid1| 11,2| Stream.cc(274) sendStartOfMessage: > HTTP Client REPLY: This is a child proxy response to the client. We need parent response to the child proxy. Look for "HTTP Server RESPONSE" lines instead.
