Help pls! authorization error

hi, I’m a graphic designer and I use the “Vectary” program to create 3d renders with Sketchfab models, today I couldn’t use the application because sketchfab gives me the following error, I can’t link sketchfab with my application to load renders "Error from authorization "invalid request, mismatched redirect url, i need to occupy sketchfab with vectary asap to create a render i need to deliver. so I need to fix it. I contacted the vectary technical service, and they told me that it is a sketchfab problem, please, I need to deliver a job, hopefully they will give me an answer.!

You should probably contact Vectary support for this, it looks like a configuration issue on their end.
