And it show like the picture below <http://squid-web-proxy-cache.1019090.n4.nabble.com/file/t377437/gitlab5.png> And I compare with other client that the traffic not through my squid proxy <http://squid-web-proxy-cache.1019090.n4.nabble.com/file/t377437/gitlab4.png> Its different. How can solved this?
