You may experience issues where TeamViewer keeps timing out unexpectedly. This article covers the reasons behind this and provides a TeamViewer connection blocked after timeout fix for smoother connectivity.
🌟Quick Summary:
TeamViewer typically times out due to one of three main reasons: stricter commercial use detection (limiting sessions to 1–5 minutes), restrictive "idle session" settings, or unstable network connections. To fix this, users should first adjust the Advanced Options to disable automatic inactivity timeouts.
If the issue persists, verify that your license channels aren't fully occupied, whitelist TeamViewer in your firewall, or consider resetting your TeamViewer ID. For users facing persistent licensing blocks, switching to a dedicated alternative like AnyViewer is often the most reliable long-term solution. You can follow this step-by-step guide to fix TeamViewer keeps timing out.
If your TeamViewer session keeps disconnecting after a short time, there are usually a few clear reasons. In most cases, the issue is related to license limits, inactivity settings, unstable internet, or security software blocking the connection. Understanding the exact cause can help you fix the problem quickly and avoid repeated interruptions.
Below is a simple overview of the common causes and solutions.
| Cause | What Happens | How to Fix It |
|---|---|---|
| Commercial use detected | The session ends after 1 or 5 minutes. You may see a license session limit exceeded error or receive a message saying the connection is blocked. | If you use it for business, buy a license. If you only use it for personal help, submit a review request on the official website. |
| Idle session timeout | The session disconnects when there is no mouse or keyboard activity. | Go to Settings, then Advanced, and find the inactive session timeout option. Turn it off or increase the time limit. |
| Unstable internet connection | The connection drops suddenly without warning. | Make sure both devices have stable internet. You can also disable UDP in Advanced network settings to improve stability. |
| Firewall, antivirus, or VPN interference | The session disconnects unexpectedly due to blocked traffic. | Add TeamViewer to the whitelist in your firewall or antivirus. Update the software on both devices. |
In summary, TeamViewer usually times out because of license restrictions, inactivity settings, network problems, or security software conflicts. First, check whether your usage matches the free version rules. Then review your timeout settings and internet stability. If the issue continues, adjust your firewall or antivirus settings. By checking these areas one by one, you can normally solve the problem and maintain a stable remote connection.
If TeamViewer keeps timing out, it may be caused by inactive sessions or channels being used for too long. You can control how long a session stays open without activity. Setting an automatic timeout helps free up channels and prevents unnecessary disconnections.
Step 1. Open TeamViewer and click the Gear icon in the upper right corner to open Settings.
Step 2. Go to Advanced and then click Advanced settings for connections to other computers.
Step 3. Find the option called Timing out inactive sessions.
Step 4. Choose a time period. After this period of no activity, the remote session will close automatically.
Step 5. Click OK to save the changes.
You can also apply this setting to all devices under your license by using a TeamViewer Settings Policy. This is useful if you manage multiple computers.
After setting the automatic timeout, you can also check whether all your channels are currently in use, which may be another reason for connection issues.
TeamViewer may time out if no channel is available. Each license has a limited number of channels. If all channels are being used, new connections cannot be established until one session ends.
Step 1. Open TeamViewer on your Windows computer.
Step 2. Click Help in the top menu.
Step 3. Select About TeamViewer.
Step 4. Click Channel Usage in the About window to see which TeamViewer ID is currently using a channel.
Step 5. End any unnecessary or forgotten sessions manually if possible.
TeamViewer can only show the TeamViewer ID using the channel. It does not show the device name or the user who is signed in.
If you still experience timeout problems after checking channel usage, you may need to review your network stability or upgrade your license for more channels. About TeamViewer free vs paid, here is an article can help you.

Step 2. You should now see that you have successfully logged into AnyViewer. Your device will be assigned to the account automatically and listed on My devices list once logged in.

Resetting the TeamViewer ID is a complex process that involves modifying system settings and hardware-related information. This method works by removing old TeamViewer records and changing certain system identifiers so that a new ID can be generated. Please follow each step carefully and make sure you have administrator rights before making any changes to the registry or system files.
Step 1. Stop the TeamViewer service from the Windows Services panel to make sure the program is fully closed. Then press Win + R, type regedit, and open the Registry Editor. Go to HKEY_CURRENT_USER > Software > TeamViewer and delete the entire TeamViewer folder.
Step 2. Open PowerShell as an administrator and run:
Get-Item "C:\Program Files" | select Name, CreationTime
Check the current CreationTime value. Then use NirCMD in an elevated Command Prompt to change the folder time with:
nircmdc.exe setfilefoldertime "C:\Program Files" now now
Run the PowerShell command again to confirm the time has changed.
Step 3. Change the MAC address of your network adapter. First, open Command Prompt and type ipconfig /all to find your adapter name and current Physical Address. Then go to HKLM > SYSTEM > CurrentControlSet > Control > Class > {4d36e972-e325-11ce-bfc1-08002be10318} in Registry Editor. Locate your adapter by checking the DriverDesc value. Edit the NetworkAddress entry and modify at least one digit of the MAC address.
Step 4. Download and extract the VolumeID tool. Open Command Prompt as administrator and type vol to see the current Volume Serial Number. Use the VolumeID tool to replace it with a new serial number by slightly changing the existing value.
Step 5. Close all windows and restart your computer. After rebooting, open TeamViewer again. The system identifiers should now be refreshed, and TeamViewer should generate a new ID automatically.
After completing these steps, your system identifiers will be refreshed and TeamViewer should assign a new ID when it starts. You can see whether TeamViewer still keeps timing out.
In conclusion, TeamViewer keeps timing out mainly because of license limits, inactive session settings, channel restrictions, network instability, or security software interference. By checking each factor step by step, most users can quickly identify the real cause and fix the issue without complicated operations. If the problem continues and affects your daily work, switching to a stable alternative like AnyViewer can provide longer, smoother, and more reliable remote access. Choosing the right solution will help you maintain a steady connection and improve your remote work experience.
1. Why am I getting the "Connection blocked after timeout" error on the free version?
This usually happens because TeamViewer thinks you are using it for business. When commercial use is suspected, your sessions are limited to a few minutes and you must wait before reconnecting.
2. How do I stop TeamViewer from disconnecting when the session is idle?
Go to Settings, then Advanced, and find “Timing out inactive sessions.” Set it to Off or choose a longer time. This prevents automatic disconnection when there is no activity.
3. Is there a time limit for TeamViewer Free sessions?
For normal personal use, there is no strict short session limit. If your session ends after 1 to 5 minutes, it is likely due to commercial use detection, not the standard free version limit.
4. How can I reset my TeamViewer ID if I've been wrongly flagged for commercial use?
You need to submit a request on the official TeamViewer website. Fill out the Commercial Use Suspected form, upload the required log files, and confirm that you only use it for personal purposes.
5. Will reinstalling TeamViewer fix the timeout issue?
Usually no. The restriction is linked to your device ID, not just the app. If timeouts continue, you may consider contacting support or using a stable alternative like AnyViewer for longer and more reliable remote sessions.
