Steps to reproduce:

1. Define 2 proxies with ipv6 only in proxygroup
2. Define agent2 condiguration ServerActive=fd00::1;fd00::2 on each proxy
3. Verify proxy1 agent defaults to proxy1 proxy, proxy2 agent defaults to proxy2 proxy
4. proxy1 and proxy2 agents will not succeed sending data
5. Define agent2 condiguration ServerActive=[fd00::1]:10051;[fd00::2]:10051 on each proxy
6. proxy1 agent will succeed (first try is default proxy for this agent, proxy 2 will fail, it will be redirtected to fd00::2 but then gives error cannot connect to [fd00::2:10051]: dial tcp: address fd00::2:10051: too many colons in address
7. Change of address to name (ServerActive=proxy1,proxy2) has the same results, proxy1 agent will work, proxy2 agent gets a redirect to ipv6 including portnumer in ipaddress...

Result:
**

ipv6 addresse are interpreted wrong, port number is included in ip address.

Expected:

ipv6 address has to be interpeted without portnumber like [fd00::2]:10051
