Unable to connect to server due to firewall/network

Hey there, I tried to make the kaswynn server online to test with a friend but after clicking on the server on the launcher an error msg came up around 10 secs later saying:

Unable to connect to server due to firewall or network problem. Code:183

>>> I am using hamachi atm
