SERVFAIL on IPv6 tunnelbroker network

Is it possible that I have 2 routers on 1 server and 2 views? Should I just
use 1 connection to the same server?
I connect to to internet connection 1 for me downloading etc, and 1 for the
input for web, email, etc...
But I connected 2. The big problem is that I cannot turn off the server 2nd
view, I need exactly the 2 views and I still get a SERVFAIL, but after I do
it again, it will work, or on my workstation I have to refresh the browser
like many times.
Plus by now it cached my ip address, this is what is weird, that the first
time it is like that SERVFAIL and I have know idea what it is doing.
*Eg , the log:*
