Network Diagnostic Test failure - Error connecting to https://www.autodesk.com/products/fusion-360/collaborator

[BSD-Autodesk-Admin]

Hello Autodesk Team,

Over the last year I have been batteling issues with computer labs having issues saving projects that are shared with their teacher. The only band aid we have been able to apply to this issue was having students clear their cache which then let them save their project, or they had to save-as in order to not lose their work...not a good workflow.

Unfortunately the most recent update to fusion360 has made this issue even worse.

I was able to run a network diagnostic report when a user had the problem recently and we discovered the machine was having trouble communicating with https://www.autodesk.com/products/fusion-360/collaborator. When navigating to this URL on the affected machine it redirects to https://www.autodesk.com/products/fusion-360/team-participant?term=1-YEAR&tab=subscription

I have reviewed the following Fusion 360 Help | Ports and Domains required by Fusion 360 | Autodesk and verified all domains / ports listed in this are allowed by our firewall and network filter. I also can't find any posted information on this URL https://www.autodesk.com/products/fusion-360/collaborator or anything associated with it.

Does anyone from the autodesk team know what this URL is used for?

Indeed..same problem on start up. Offline mode only and no access to work files.

I'm now experiencing the exact same issue (noticed this after the Sept. update).

After almost 4 months since the original post about this error, no one even bothered to answer...

Good job Autodesk support team!

I have the same issue and then some. . . .

I could not reply to the originator of this thread so leaving my two cents here. My apologies.

Maybe somewhat related. Fusion 360 for the version I have, requires ports 80 and 443 to be open. However in Apples Sequoia 15.1 running on an Apple M2 Pro, there is no way in settings to configure port accessibility. Firewall rules are by application name only. Every time I run the Network Diagnostic Test it fails (as noted in this thread) which I attribute to a "port" access issue. Any recommendations on how I can run Fusion 360 in an "diagnostic" error free environment?

I am seeing this issue again in my labs after the latest update. I have posted multiple times, provided logs etc and never seem to get responses from Autodesk. Getting EDU support doesn't seem to interest them.
