Hello, nils goyvaerts
Welcome to the Microsoft community.
I understand that you are experiencing problems with TSL, here are some troubleshooting options:
- Enable TLS 1.0/1.1 with Internet Properties
As mentioned earlier, you will need to enable or turn on TLS 1.0 and TLS 1.1 on your computer to resolve this issue. Since these are not enabled by default on Windows 11 and Windows 10, you will need to do this manually. For this, you can get help from the Internet Properties panel. To enable TLS 11/10 on Windows 1.0/1.1, do the following:
- Search for Internet Properties in the Taskbar Search box.
- Click on a single search result.
- Switch to the Advanced tab.
- Find TLS 1.0 and TLS 1.1.
- Check both checkboxes.
- Click the OK button.
You may need to restart your computer to complete the job. When you are done, you will not find the above error message. To verify this, you can open the Event Viewer and check if the issue has been resolved.
However, this should only be a temporary measure, as it is not safe to use TLS 1.10 and TLS 1.1 for extended periods of time.
- Modify the registry
Press Win+R to open the Run prompt.
Type regedit > click the OK button > then click the Yes option.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
Right-click Protocols > New > Keys and name it TLS 1.2.
Right-click TLS 1.2 > New > Key and name it Client.
Right-click Client > New > DWORD (32-bit) Value.
Set the name to DisabledByDefault.
Right-click Client > New > DWORD (32-bit) Value.
Set the name to Enabled.
Double-click it and set the value data to 1.
Click the OK button.
Finally, restart the computer.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
