Hi guys,
I have the same issue, after turned on the http proxy, all clients can't access internet. This used to be working fine on 2.5.1 and 2.5.2, but after upgraded to 3.0 on last week, it's not working anymore.
Checked the proxy log file, it's empty even have it turned on.
Checked the squid log, below lines are repeating,
FATAL: No valid signing SSL certificate configured for http_port 0.0.0.0:8080
Squid Cache (Version 3.3.
: Terminated abnormally.
CPU Usage: 0.087 seconds = 0.056 user + 0.031 sys
Maximum Resident Size: 23888 KB
Page faults with physical i/o: 25
Anyone can help? Thanks
