Trusted Domain entry 11 is invalid when IPv6 is used.

Option -m4 seems to be undefined, hence curl -m4 icanhazip.com always returns IPv6.

Solution

1. if ipv6 is returned then the value should be enclosed in brackets „[]“ when set (line 16)
2. run curl -4 icanhazip.com in order to always return ipv4 (line 14)
