Having problems connecting to a private minecraft server?

Me and my friend play Minecraft together on a private server over a hamachi network. For the 2 years or so we have done this no problems have come up until now. I will join his server and be on for about 15 seconds until I get kicked for losing connection. Hamachi shows no connection problems and no one else on our server is having this problem. I have tried several things to fix this (reinstalling both Minecraft and hamachi, changing hamachi settings, rejoining the hamachi network) but nothing I have done has worked. Does anyone have any solutions for this?

Oh thats easy to fix. Simply buy a new computer and get rid of your old one. Hope that helped.
