Thank you for the detailed update @PSWONG.

Since you're using the QuickSupport version 15.70.5, please update to the latest release as a first step.

Additionally, you can check for any pending Windows updates and install them if available before trying another connection.

To better understand where the session failed after the reboot, could you let us know which connection method your IT technician used?

A. Via session link or session code or

B. Via ID and password

Once TeamViewer and Windows are fully updated, please try starting a new remote session.

If the error appears again, feel free to share more details. We're always here to continue supporting you in the Community. Just let us know how it goes!

Best,

Hi SophE,

Thank you for your response.

I am writing to answer your questions as follows:

A remote connection was initiated to address an issue with my D: drive disappearing. During the session, the IT personnel decided to reboot my PC. However, when they attempted to reconnect remotely afterward, an error message appeared: "Error code: mWQpTvA3vzg-3--5D-7JC," and the reconnection ultimately failed.

I was using the TeamViewer Quick Support module.

Yes, I am using the TeamViewer version installed on my PC.

The operating system on my PC is Windows 10.

Unfortunately, I did not take a screenshot of the error message at the time. Please find attached screenshots of the TeamViewer properties and the TV15Install part file for your reference.

Please let me know if you need any further details.

Cheers,

PSWONG
