Information

 
Answer

Symptom

Connection is lost and you receive a Windows Socket Error 10054.

Cause

Error 10054 occurs when the connection is reset by the peer application, usually due to an incorrect firewall configuration. Find more information about this error on Microsoft Development Center.

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.

DomainDescription
*.logmein.comLogMeIn main site
*.logmeinrescue.comPowers the LogMeIn Rescue service
*.logmeinrescue-enterprise.comPowers account-specific Rescue features (not required on normal accounts)
*.logme.inLogMeIn common login service allowing login to LogMeIn.com, join.me, and cubby.com
*.hamachi.ccPowers the LogMeIn Hamachi service
*.internapcdn.netPowers updates to multiple LogMeIn products
*.LogMeIn123.comSite to connect to a LogMeIn Rescue technician
*.123rescue.comSite to connect to a LogMeIn Rescue technician
*.support.meSite to connect to a LogMeIn Rescue technician
*.join.meConferencing and screen sharing service by LogMeIn
*.cub.byRedirects to Cubby services
*.cubby.comCoud storage and syncing 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.
