Hey @imaduddinsyed09 ,

Sorry to hear you are experiencing that! Just to check - have you been able to log into Fusion 360 before, on this same network? Are you using a home internet network?

Can you please collect your application log files and post them here? 

Thanks,

[imaduddinsyed09]

Hey @James.Youmatz, 

After installing Fusion 360, I log into it then I get this error.

And yes, I am using a home internet network. 

I attached my application log files in the form of a zip folder.

[imaduddinsyed09]

The above zip folder is inside "C:\Users\DELL\AppData\Local\Autodesk\Autodesk Fusion 360"

I attach the other two zip folders,

"first_logs" folder is inside -> "C:\Users\DELL\AppData\Local\Autodesk\Autodesk Fusion 360\7HUKQKEW8H87"

and "second_logs" folder is inside -> "C:\Users\DELL\AppData\Local\Autodesk\Autodesk Fusion 360\CFT5M9B5WUF7"

Hi @imaduddinsyed09 ,

It looks like some URLs may be having a hard time being reached. From the logs:

20210916T164254 W 1784 Reqest: Call failed: https://js.prd.fusionapi.autodesk.com/fusion360-runtime-config/config.json : WinHttpSendRequest: 12029: A connection with the server could not be established

It states that a connection with the server could not be established. Do you have any anti-virus or network policies that may be prohibiting that URL from being reached?

Thanks,

[imaduddinsyed09]

@James.Youmatz, I haven't any anti-virus or network policies.

Hi @imaduddinsyed09 ,

Interesting. Something is causing that network call to fail - and likely why you see that sign in failure.

What happens when you try to access https://js.prd.fusionapi.autodesk.com/fusion360-runtime-config/config.jsonin a web browser? Does it succeed and show text? Or is it blocked?

Can you successfully access and login to login.autodesk360.com?

Has Fusion 360 ever worked on this computer before?

Thanks,

[imaduddinsyed09]

 This URL -> "https://js.prd.fusionapi.autodesk.com/fusion360-runtime-config/config.json"  shows the text and it is not blocked.

Yes, I am successfully access and login to login.autodesk360.com

No, Fusion 360 never worked on this computer before and it shows the above-mentioned errors since I installed it.

[James.Youmatz]

Do you have the ability to test on a different network or hotspot? I'm also wondering if resetting your router may do the trick.

James

[imaduddinsyed09]

Yeah, I already tested it on three different networks...
