Oh, you're not actually using "IPv6-local1" here but the actual IP. That confused me for a while how this error could happen. Anyway that part of the code attempts to find :port from the string. So you have two possibilities:

a) Don't define IPv6 address, but a hostname and in /etc/hosts map it into the actual IPv6 address

b) Append :port after the address (it'll look ugly/confusing, but should work for now - maybe in future it gets changed though)
