Unable to launch: Network Diagnostic Test error

Fusion will not launch, tried repair reset and reinstall, but made no difference.

Ran Network Diagnostic Test and got an error on this line:

@thomas_buckleyEMA7C

Please try below steps to install Fusion.
1. Make sure that Fusion installer is not running in task manager
2. Go to %localappdata%\Autodesk\ then DELETE the following folders – Webdeploy, Web Services, Identity services, Autodesk Fusion 360 ((IF you do not have any other Autodesk products installed, delete the Full Autodesk folder)
3. Delete the shortcut that is used to launch Fusion
4. Restart your machine
5. Do not use the same Fusion installer. Can you please download the installer again
6. Now install again

I tried this but still no difference.

Just loads to a white window with Autodesk Fusion at the top left as it did before.

I have attached the Network Diagnostic Test that has an error, would this be the cause of the problem?

@thomas_buckleyEMA7C @The network check failing is likely not the issue.

can you attach an image of the screen you see when you launch Fusion?

Is this the first time you are using Fusion? (That is do you already have an account or this is the first you are creating an account?).

Hi,

It has just decided to start working again! After spending the whole day trouble shooting it, I turned my computer on today and it now it works for no apparent reason, very confusing!!!

I have been using Fusion for over 2 years.

Thanks

Tom

@thomas_buckleyEMA7C Good to know that it is working but I have no explanation at this time on what could have happened yesterday.

Fusion stopped working again on my windows laptop again a day or 2 later. It works okay on a smaller and slower laptop I have, but not my preferred laptop.

I have attached a screenshot of where it get stuck loading.
