Connection Error: The server connection is not established.

[Brian H]

Upon launching STM32 CubeProgrammer today, I encountered this dialog:

In case the image doesn't show, the text reads:

The server connection is not established.
The network connection is required to download updates.
Please check your Proxy Settings.

This thread refers to the same error and is marked "Solved" but the solved problem is actually a different error, described in the same thread.

This message does not interfere with programming, but I'd sure like it to go away.

Using Windows 10 64Bits and a fresh install that is STMCubeProgrammer 2.20, the proxy connexion fails as it was previously described.

Fortunatelly, the solution in downgrading to 2.16 has worked.
