It could be several different things, but I think it might be the settings of the "Idle Time Allowed".
Start to connect to the computer, enter the passcode, and then instead of clicking REMOTE CONTROL, click on PREFERENCES. Click on the first option - REMOTE CONTROL SETTINGS. In the top box, labeled GENERAL, look about half way down (in the box) for an option that says "Idle Time Allowed". It is probably set for about 10 or 20 minutes. Boost it up to whatever you think is necessary.
If it is set for 20 minutes, if you are idle for that long, you will be disconnected.
Hope this helps you with your problem.
(DISCLAIMER: I am NOT an employee of LMI, nor do I have any financial concern in LMI. I am strictly a HAPPY USER of LMI products. I am using PC version and XP SP2. Other systems or versions may act different than described above.)
One of three things happened:
1 -- Your session timed out due to inactivity (or just because it felt like it) as KGHalbe mentions above.
2 -- The computer shut down or restarted (this could either be you or someone physically present.)
3 -- The computer was knocked offline for any variety of reasons, and is no longer connected to the internet as far as LMI is concerned.
The LMI service on the remote computer is either off or the computer is restarting. This sometimes causes it to appear online but when you click connect it bounces you right back to your computer list with your error message in red letters at the top of the web page.
If it persists more than 20 minutes you need to visit that machine and either reboot it or issue these commands from a DOS prompt
I had the same problem when i tried to reboot/logoff-login back to my pc. I enabled windows auto-login feature to solve this problem. Note that this has a drawback that username/password is stored in registry as plain text. Hope it helps.
In addition to what others have said, it is also possible that the version of LogMeIn installed on the target PC needs to be updated. I ran into the same problem when using Mozilla Firefox v3.x to connect to LogMeIn Free v3.0.606. I was able to connect with IE v7. So I used IE to connect to the target PC and updated LMI to v4.x. After the upgrade of LMI, Firefox connected without a problem.
Which Web browser are you using? What version of LogMeIn is installed on the target PC?
