[squid-users] TCP_MISS/419

Mon Dec 5 18:28:19 UTC 2016

Dear, 
I ask for help to resolve a connection failure with a particular site. 
See the logs below. Even the log showing DENIED, I do not get denied access message. 
One of the codes below that I did not find in the Squid FAQ is TCP_MISS / 419. Can anyone tell me what this error means? 

What happens: 
When we log in to the site, when accessing features, it simply goes back to the login screen. 
I did a test passing outside the proxy, the problem does not happen. 
I tested on 2 different proxy (Pfsense and Endian). 
Can anybody help me ?
