Linux AppImage LeoCAD-Linux-21.06-x86_64.AppImage has a strange error about "connecting" to update server

[yngmjgsd]

Describe the bug Cannot connect to update server on Linux (Kubuntu 22.04 was tested)

To Reproduce Steps to reproduce the behavior:

1. Go to 'Help' menu
2. Click on 'Check for Updates...'
3. See error "Error connecting to the update server."

Expected behavior Must show successful results cause the application compiled from the source (using QtCreator and Qt 5.15.2) works just fine on the same system which doesn't explain what is wrong with the source code, or system configuration.

Screenshots This is how it looks.

Version (please complete the following information):

• OS: Kubuntu 22.04
• LeoCAD Version 21.06, from LeoCAD-Linux-21.06-x86_64.AppImage file

Crash information: No crash.

The actual question is - is there any specifics for AppImage 21.06 here? The version compiled from sources works just fine.
