Hi,
I have two parent proxies configured, but Squid seems to stick to the default proxy even when the proxy cannot be reached:
2017/03/15 06:40:13 kid1| TCP connection to proxy.mycompany.de/8080 failed
2017/03/15 06:40:13 kid1| Detected DEAD Parent: proxy.mycompany.de

2017/03/15 06:40:43 kid1| TCP connection to proxy.mycompany.de/8080 failed
No failover takes place... I must miss someting in my config. Can someone please help me. I am on Ubuntu 16.04.2:
