Action

Check the following items to ensure that your system, firewall and router are configured correctly.

Solution 1: Verify that LogMeIn domains are whitelisted in your firewall/router configuration.

Domain Description
*.logmein.com LogMeIn main site
*.logmeinrescue.com Powers the LogMeIn Rescue service
*.logmeinrescue-enterprise.com Powers account-specific Rescue features (not required on normal accounts)
*.logme.in LogMeIn common login service allowing login to LogMeIn.com, join.me, and cubby.com
*.hamachi.cc Powers the LogMeIn Hamachi service
*.internapcdn.net Powers updates to multiple LogMeIn products
*.LogMeIn123.com Site to connect to a LogMeIn Rescue technician
*.123rescue.com Site to connect to a LogMeIn Rescue technician
*.support.me Site to connect to a LogMeIn Rescue technician
*.join.me Conferencing and screen sharing service by LogMeIn
 


Solution 2: Is the computer behind a Sonic Firewall or another type of firewall? Your Intrusion Detection may be blocking LogMeIn.

  1. Temporarily disable any features related to Intrusion Detection.
  2. Try connecting again to test whether Intrusion Detection is interfering with the LogMeIn service.
  3. If the problem persists, continue to Solution 3.
 

Solution 3: Disable peer-to-peer functionality in LogMeIn.

On certain systems the issue occurs when LogMeIn is connected via a peer-to-peer connection. To disable this functionality, you must edit a registry key.
Note: Only attempt this if you are comfortable modifying the Windows registry. Changes may cause system instability or even prevent Windows from starting. Contact LogMeIn Support if you need assistance.
  1. Go to Start Menu > Run.
  2. Type regedit and press Enter.
  3. Navigate to the following folder: HKEY_LOCAL_MACHINE\SOFTWARE\LogMeIn\V5\Net\NATUDP
  4. Change the DisableEx (REG_DWORD) key from 0 to 1.
  5. Close the Registry Editor.
  6. Go to Start Menu > Run.
  7. Type services.msc and press Enter.
  8. Locate the LogMeIn service.
  9. Click Restart.
  10. Reconnect via LogMeIn and check if you still get disconnected.
If the problem still persists, contact LogMeIn support.
