Hi, most times we encountered this error message it had something to do with IPv4 DNS queries being answered too slowly or not at all (as in: only AAAA-records in the reply). If this occurring with some sites only, that could be the case. You could verify this by sniffing your DNS queries from the squid. We solved >99% of these error with the following two lines - a couple of sites needed entries in /etc/hosts, because their nameservers were broken. > dns_timeout 10 seconds > forward_max_tries 25 Kind regards, Jascha Sticher -----Ursprüngliche Nachricht----- Von: squid-users <squid-users-bounces@xxxxxxxxxxxxxxxxxxxxx> Im Auftrag von Ahmad, Sarfaraz Gesendet: Dienstag, 7.

This is intermittent. In Chrome's dev tools, it appeared to take over 20 secs to setup the TCP connection. I am SSL bumping all TLS connections unless they match certain ACLs. So it is safe to assume that the vast majority of the traffic was bumped. I don't see any TLS handshake failure messages in cache.log. I think the access.log messages I posted earlier are fake CONNECT requests created using TCP-level info (the response time logged there is directly proportionate to what I see in Chrome's dev tools). Guessing that Squid would send TCP SYN-ACK only after it receives SYN-ACK from remote/origin server. I don’t think ICAP(reqmod) would come into the picture yet either (assuming that even the TCP connections have not been set up yet) so that is safe to rule out. Am I right here ? Also restarting squid service fixed this. I had a python script running in the background that was able to GET a webpage using requests module(timeout set to 30) but Squid apparently couldn't even set up a TCP connection. - Sarfaraz -----Original Message----- From: squid-users <squid-users-bounces@xxxxxxxxxxxxxxxxxxxxx> On Behalf Of Amos Jeffries Sent: Tuesday, August 7, 2018 6:04 PM To: squid-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: Squid returns NONE_ABORTED/000 and high response time but the internet access itself looks okay On 07/08/18 21:55, Ahmad, Sarfaraz wrote: > Hi, > > > > I am WCCPv2 for redirecting traffic to Squid. > Squid version? > Intermittently I see these messages in access.log and the internet for > clients goes away. > > > > 1533612202.312 79102 <ip> NONE_ABORTED/000 0 CONNECT > 198.22.156.64:443 > - HIER_NONE/- - > > 1533612202.312 82632 <ip> NONE_ABORTED/000 0 CONNECT > 173.194.142.186:443 - HIER_NONE/- - > > 1533612202.312 16030 <ip> NONE_ABORTED/000 0 CONNECT > 172.217.15.67:443 > - HIER_NONE/- - > > 1533612202.312 78477 <ip> NONE_ABORTED/000 0 CONNECT > 173.194.142.186:443 - HIER_NONE/- - > > > > But I can access internet on the host running squid itself just fine > yet Squid reports those messages with high response times (the second column). > ...> > > We use an ICAP service.

It's probably not a port-80 style CONNECT request. What does Squid send back to the client? Does Squid complete the TLS handshake? What are your SSL-Bump settings?
