Talk:Tutorial: Proxy Connection/@comment-27583915-20160110100053

I used Cookie and also VPN methods. This is what I get from those 2:

GET http://www.googletagmanager.com/gtm.js?id=GTM-J5ZH net::ERR_BLOCKED_BY_CLIENT

and

503 (Service Unavailable: Back-end server is at capacity)

/

What should I do to fix those 2 errors!?
