Hello,
Just sharing this information. If you find yourself not able to patch Mabinogi due to the error, "Can't connect to FTP server ", the solution is to add this on your localhosts in your hosts.txt file at "C:\Windows\System32\drivers\etc". Add this entry to local host:
174.35.24.78 mabipatch.nexon.net
Then save the the txt.
I had issues earlier, so just letting others know if you happened to look here lol
