I would not consider your squid to be the problem. I have several squids (2.7 and 3.11) connected to various upstream proxies (other squids, but also private, custom-written proxies), running on same or other machines, and can not remember your problem. May be, you could toggle persistent conns to upstream server on/off, or try to only use HTTP/1.0 with upstream, just to eliminate this potential problem area. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/TCP-connection-to-upstream-proxy-failed-tp4664262p4664265.html Sent from the Squid - Users mailing list archive at Nabble.com.
