Hamachi on Vista: Mediation server has rejected your login request
2 December 2008
After upgrading to the latest version of Hamachi, I kept receiving this error: “Mediation server has rejected your login request.” I ran through the solutions on the Hamachi site and none of them worked. Here’s what did:
Disable Windows Firewall (Through Your Control Panel).
Rename Hamachi Folder in %APPDATA%
Create new account, DO NOT use the same username as last time.
