Facing login issue - very slow response from SketchUp

I have taken subscription 16 days back for Sketchup pro but still unable to login into desktop Application. Sent email to sketch up and there is very slow response from them and not understanding the issue. sending some usefulness links.

Seems like my money is lost.

I have sent a classic license as a work around for now. One thing to try, before adding the classic license, where you see 127.0.0.1, try changing that to localhost.

So, the URL that cannot be reached would start with localhost:54039/signin instead of 127.0.0.1:54039/signin. Then hit Enter, and see if the sign in succeeds.

What environment? Citrix?
