Why is TeamViewer timing out?

TeamViewer, a fantastic remote desktop software, enables users to access unattended computers easily and offers personal licenses. As we all know, a personal license of TeamViewer is free; other forms of a license, including business, premium, and corporate, are paid.

Based on user feedback, the above error typically happens to free license users and sometimes to paid license users. If you’re a paid license user, there might be a licensing issue. The quickest solution is to contact the support team directly; they will be happy to assist you. 

If you’re a free license user, this message tells you that your free license is limited. You have surpassed the TeamViewer time limit for free-user connections or been detected as using it for commercial purposes. Another similar information you might also receive for TeamViewer commercial use detected:

"We are sorry for the interruption. Unfortunately, we will have to limit your usage of TeamViewer because the usage pattern suggests that you have been supporting others professionally. To continue using Teamviewer, please subscribe to a license plan."

How to fix “Connection blocked after timeout” TeamViewer

There are generally four solutions to the  TeamViewer “Connection blocked after timeout” error if you’re a free license user. First, you can wait for a moment or restart the app and then try again. But this won’t work every time. Second, you can try to reset the TeamViewer ID. The third is to upgrade and activate a paid TeamViewer license. The final is to try a TeamViewer alternative.

Solution 1. Restart the app and try again

Step 1. Press Win + R, type in “services.msc”, then click OK.

Step 2. Find TeamViewer. Right-click it and then choose Restart.

Step 3. Wait for the process to finish. Then try to connect via TeamViewer again.

Solution 2. Reset the TeamViewer ID

Step 1. Follow the steps above to stop TeamViewer from the Services first.

Step 2. Open Registry Editor by entering “regedit.exe” in the Run box. Navigate to: HKEY_CURRENT_USER > Software > TeamViewer. Delete the TeamViewer registry key.

Step 3. Open the PowerShell console with administrator privileges and run the following command to determine the creation date of the "C:Program Files" folder:

Get-Item "C:\Program Files" | select Name,CreationTime

Step 4.Use the NirCMD tool to change the creation date of the Program Files folder. Download it and run it from the elevated Command Prompt console as follows:

nircmdc.exe setfilefoldertime "C:\Program Files" now now

Step 5. Check if the CreationTime value of the directory has changed.

Step 6. Then, using one of the special tools available, change the MAC address of your network card. Alternatively, you can edit your MAC address through the registry by following the steps outlined below.

Step 7. To get the current MAC address of your network card, open command prompt, and run the following command:

Ipconfig /all

Pay attention to two parameters: Description (LAN card description) and Physical Address (MAC address).

Step 8. Then, open the Registry Editor again and go to the key: HKLM > SYSTEM > CurrentControlSet > Control > Class > {4d36e972-e325-11ce-bfc1-08002be10318}.

Step 9. Find DriverDesc option, where the description (name) of your NIC must be specified (for example, Intel(R) 82574L Gigabit Network Connection). When you've found the correct network card, double-click the NetworkAddress parameter. It specifies the network card's MAC (hardware) address. It is sufficient to change a single digit in the current MAC address, such as 000C299D4D80.

Step 10. As a result, the network card's MAC address is changed. You must now modify the VolumeID of the system partition. VolumeID (or Volume Serial Number) is a hard drive volume's unique identifier that is set during formatting. Use the console utility VolumeID v2.1 to change the VolumeID v2.1. VolumeId.zip should be downloaded and extracted.

Step 11. Open Command Prompt with Administrator privileges and run the following command to determine the current VolumeID:

vol

Volume Serial Number is 5E37-ECE1.

Step 12. Replace the current value with the new value 5E37-EC11:

c:\users\root\Downloads\VolumeID

Volumeid.exe c: 5E37-EC11

Step 13. Close the command prompt and restart your computer. Then restart TeamViewer, and you'll be given a new TeamViewer ID.

Solution 3. Upgrade and activate a paid license

As we mentioned before, TeamViewer non-commercial use timeout happens because you have surpassed the TeamViewer time limit for free-user connections or you have been detected as using it for commercial purposes. So the third solution is to purchase and activate a paid license for it to work better.
