I read pther questions and i heared about enabling unptp or something like that on my connection options. When i get to my connection options (Unpon typing in my IP adress in the web search bar) I cant find anything to do with uptp. I did use to run a regular minecraft server on my computer for my friends, so i am port forwarded to 25565(Minecraft)
 
Thanks.

The errors you are getting mean YAMS wasn't able to portforward for you, most likely because it couldn't detect a UPnP capable router.

If you know how to manually port forward, then just disable the port forwarding options in YAMS.

Otherwise you will need to remove the manual port forwards, enable UPnP on your *router* and make sure the UPnP security mode is set to low.
