You have configured Squid to:
1) "no-vhost" - ignore the Host header the client sent indicating what
domain name it was contacting.
2) defaultsite=184.108.40.206 - use "220.127.116.11" as the domain *name*
for all requests received through that https_port.
Why would you expect to see anything other than https://18.104.22.168 in
the URL when you have configured those?

Your use of "physically" seems to be incorrect. You walked up to the
machine hardware and did what ?
"Clicking" seems to be that you logged in (not physically) and changed
something which affected how Squid was able to connect to it.
All traffic with the domain name "22.214.171.124" and not the path
"/portal6may" gets sent to the second cache_peer (172.20.36.150).
So what do you expect to happen when the server 172.20.36.150 receives a
request with Host: header domain name set to "126.96.36.199" ?
It seems like the servers connectivity is a bit flakey and getting
disconnected occasionally. But the wrong Squid configuration could be
hiding some other issue.
