Fusion 360 times out while still loading

[dtaylorAXCYG]

I am an IT administrator in UK education trying to get Fusion 360 Browser access to work in my school. I haven't managed to get it to run yet - I keep getting session disconnected due to inactivity while the program is still loading, sometimes at 2-3% and sometimes as much as 50%. I am aware of website allowances which I believe are all in the filter and nothing reporting as being blocked. I am aware of <600ms ping to us East coast - mine tests at 190-200 to California. running i5 12th Gen with 16gb ram on 200mb internet connection. tried other machines of different spec and get similar results. hoping for a glimmer of a hint of a clue where to look next.

Hi, sorry about the issue you are facing. In order to troubleshoot, we need the browser's har file. Can you please send it to guillermo.melantoni@autodesk.com? 

Thanks!

I'm attaching 2 files - the first it went all the way through to 100%, sat there for a couple of minutes then failed. the second was a repeat of the issues I saw yesterday - failing after only a couple of percent downloaded. (smaller file)

Regards,

Derek.
