Warning:"No internet connection" when starting TouchGFX-Designer. Although the other STM applications (Prg, MX etc) are working fine and get their updates via internet without any problem. The TouchGFXdesigner starts only without internet connection.

Hello @GWowe.1​ ,

Which version of Windows are you using ? Because Windows 7 & 8 are not supported anymore on the latest versions of TouchGFXDesigner. This is usually the main cause of those "internet connection" issues.

If you are using Windows 10, please close TouchGFXDesigner, open a browser and ensure that you got access to internet, and then re-open TouchGFXDesigner.

Let me know how it's going,

Hello Yoann,

Thank you very much for the immediate reply.

I use Windows version 8.1. Which version of TouchGFX should I use ?

Hi,

I think that the latest version of TGFX that supports Windows 8.1 must be 4.16.1.

Can you please try with this version and let me know if you got another issue ?

Thanks,
