Think i found the problem, when IPv6 is enabled it connects then disconnects in cycles. I replicated this with a WORKING connection i have (when IPv6 isnt ticked, works fine, when its ticked it does the connected, not connected thing over and over)..
I thought the IPv6 was an "option", so it would use it IF it can, well as all the connectons are over the internet it needs to be IPv4, when i turn off IPv6, the connection works...
See image, please advise.
