I’ve found that I can no longer connect to that PC

There was an error rendering this rich post.

Dear TeamViewer Support,

About a year ago, I was able to access all my devices via the TeamViewer web interface — including my PC located in Spain.

Recently, I’ve found that I can no longer connect to that PC, even though I haven’t changed any configuration settings.

The computer is powered on and connected to the internet, but unfortunately, there is currently no one on-site who can provide me with the current session password.

The PC was linked to my TeamViewer account, and I previously had full access via the web portal without needing a password.

Could you please check whether any changes have been made on TeamViewer’s side that might affect connectivity? Is there any way to re-establish remote access?

Thank you in advance for your assistance.

Kind regards,

That is, indeed, an unfortunate situation given the fact that you need to access important documents.

For obvious security reasons, we do not have access to any information regarding the password of your remote device; no one at TeamViewer can provide you with this information, as passwords are fully encrypted and only available for the device's user (in this case, you).

If under Settings ➜ Advanced settings ➜ Random password after each session is set to Generate new, it is expected that after you shut down your computer, the password changes and is now incorrect.

I am afraid there's not much we can do. The only way out is to get someone to start your remote computer and give you access via the random password shown on your TeamViewer interface.

We thank you in advance for your understanding.

Hi @GuidoNommesen,

Great to see you posting again!

It's difficult to determine exactly why you no longer have access from a technical standpoint. However, I can confirm that we haven’t made any changes on our end that would revoke access from remote devices.

If unattended access was configured correctly, there should be nothing on our side preventing a connection.

I recommend that the next time someone is available to provide the random password, you connect to the remote device and verify the following:

The device is added as a managed device.
Unattended access is properly configured.

You can find our best practices for setting this up here: https://www.teamviewer.com/en/global/support/knowledge-base/teamviewer-remote/remote-control/provide-unattended-remote-support/

Let me know if you have any questions! I'll be happy to help you further.

Thank you for the kind response — unfortunately, it doesn't really help in my specific case.

There is currently no one on-site in Spain; I am in Germany.

I now no longer have access to important documents, which is a serious problem. I realize that I should have tested remote access more thoroughly before my departure — that’s on me.

However, before I left, I took a screenshot of the TeamViewer ID and password. Then I shut down the PC properly.

Back in Germany, I turned the PC back on using a smart plug and attempted to connect using the saved ID and password — but now the password is reported as incorrect.

From my perspective, I don’t believe I made any major mistakes. The PC was set up correctly, I had the password, yet I can no longer access it.

I would greatly appreciate it if there’s any way you could help me regain remote access to the machine.
