If you have problem connecting to skunck server when playing okremix, you need an updated version of okremix. The thing is that the old version have the same workshopID nr 740534444 as the updated version.
Two ways to download the updated version:
File at Steam https://steamcommunity.com/sharedfiles/filedetails/?id=740534444
File at skunck.se http://skunck.dyndns.org/?post_type=wpdmpro&p=2799&preview=true
On the client side replace the okremix.pk3 file. Search for 740534444 in your pc. In my case(client) the file was located in D:\Steam\steamapps\workshop\content\282440\740534444\okremix.pk3
