[squid-users] HTTP 503 error in squid proxy server

Sat Nov 7 08:30:04 UTC 2015

Dear

I have question about HTTPS communication through Squid Proxy Server.

HTTP 503 error frequency occurs.

10.xx.xx.xx - - [01/Nov/2015:03:44:33 +0900] "CONNECT xxxx.xxxx.xxx.io:443
HTTP/1.1" 503 0 "-" "Javaa/1.7.0_71" TCP_MISS:DIRECT

xxxx.xxxx.xxx.io:443 is ELB (Internet-Facing Load Balancer) DNS name.

Squid cache is disable.

My addition squid config is the following.

visible_hostname unknown
strip_query_terms off
acl NOCACHE src all
cache deny NOCACHE

What could be considered the cause?
