This window pops up although I have full connection to the internet. What could be the reason for this ? I would think that it would be better to give: You are all up to date or something similiar

Several others have reported a similar thing. FWIW, there haven’t been any updates to SketchUp 2019 since 2019.
You can download the latest available versions of SketchUp from sketchup.co/download/all.
Thanks DaveR I have the newest one 2023 Pro but wanted to check if there was a newer version

There isn’t a newer version of SketchUp yet. Please update your forum profile. It shows you are still using 2019 which is what I was going by when I made my previous post.
All done updating
