Shrirang,
That one also does not work, but I get a different message:
Hub is being configured
Please wait...
I have also tried that link many times from the two computers that I previously mentioned. I get the same message using either Internet Explorer or Chrome. On several occasions I have left this running for thirty minutes to an hour. My recollection is that I eventually get some kind of timeout error. The background picture keeps changing, so it does not freeze, but it never advances to the next screen. I opened a ticket on this one, but the person helping me thought that it had to do with my level of subscription, so I did not take that any further.
If it helps, I can delete everything from Autodesk 360. At one point there were multiple weird files that showed up after I tried to login to either autodesk360 or Fusion 360. I deleted those and kept the files that I had stored on Autodesk 360 that had been created in Inventor. I have used Autodesk 360 file storage for a while; it may have had a different name in the past and at one point I believe that I got a message about migration. I have other copies of everything that is in Autodesk 360 if it needs to be reinitialized.
Thanks for looking into this problem.
Michael
