I have a vertex tools 2 license, but I cannot activate it, it gives me a site connection error, how can I solve it.

Your profile says you are using SketchUp for Schools. That version has no facility for using extensions so there’s no way you could install it.

I have sketchup pro, I don’t know how to change it in the profile.

Looks like you already did that.

What is the error specifically? Maybe @colin will have a suggestion.

Don’t have suggestions, but I edited the first post so you can see the screenshot.

Maybe @thomthom has ideas.
