i made a model at sketchup 2022 from scratch, tagged the surfaces with the Sefaira extension and it worked properly, i can made the analysis ok.
then i upload the model to the web and everything seams to be fine
and after 10 15 minutes software working
the process cut down and display an error “A technical error occurred while contacting the server”
this is the model i get the error:
