SSL Decryption Blocking Sketchup on the web

We are using Sketchup on the web in our school but our Firewall has SSL Scanning on and it seems that this is blocking it from working. I’ve added https://app.sketchup.com as an exception but it’s still being blocked. Does anyone have a list of urls that need to be added as exceptions?

Thanks in advance

I’ve resolved this issue now, which was to do with our Firewall blocking zip files. It looks like Sketchup downloads a template zip file, which once added as an exception, seems to fix the issue
