That’s odd. Does the problem persist? I checked the SSL certificate on www.xltoolbox.net, it’s valid.

Can you access www.xltoolbox.net with your browser? I guess you can, otherwise you would have difficulties accessing this forum.

The update information is read from https://www.xltoolbox.net/version-ng.txt – can you access this file with your browser?

Hi Daniel,

yes it is persistent no chance the error message is almost instant after i hit the button.
Yes i can acces the txt link and this forum all from the same machine.

regards,
michael

Hm. Why would Office have trouble connecting via SSL if Windows doesn’t??? If this makes Excel +/- the Toolbox unusable for you, you can manually change the settings related to checking for updates in %appdata%\XL Toolbox\user\settings.yml:

LastUpdateCheck: 2099-03-02T00:00:00.0000000+01:00
EnableUpdateChecks: false

Either set the date of the last update check to something in the far future (e.g. 2099) or simply disable the checks altogether, as shown.

It’s unlikely that I will be able to publish any substantial updates for the foreseeable future, and if I do, I’ll certainly post it on the website or on the forum etc.
