Which ca-cert bundle or location does Fusion use on Windows 11? "Server Verification Warning" (unable to validate certificate)

Which ca-cert bundle or location does Fusion use on Windows 11? "Server Verification Warning" (unable to validate certificate)

I've been suffering the below (see screenshot) for months now (years maybe even).


Does anyone know what CA bundle fusion is using (what file, or, what store it uses?)


Screenshot 2024-04-03 183509.png

trusting failures is obviously a very poor security decision, so I want to fix it.  I find this in my logs:-


20240403T201644 E 9776 GET 60 dt=0.53 schannel: CertGetCertificateChain trust error CERT_TRUST_IS_UNTRUSTED_ROOT
20240403T201744 E 9776 GET 60 dt=0.66 schannel: CertGetCertificateChain trust error CERT_TRUST_IS_UNTRUSTED_ROOT


but I can load no problem on the same PC in:-


curl from commandlne

edge browser


python (example below)

... so it looks like every ca-store I can think of of my box is just-fine.


I've erased and reinstalled all my windows certificates

my machine is up-to-date (with correct time etc)

I do not use proxies, and I've tried with my A/V turned off (yes "CERT_TRUST_IS_UNTRUSTED_ROOT" has nothing to do with those things, but I tried them anyhow) 

I've tried everything in the help page

I've uninstalled and reinstalled Fusion

I've done the service-tool repair


Anyone got any ideas?


I do notice, when doing a "dir /s /a *.crt",  "dir /s /a *.pem" in the AutoDesk program root folder that there's a bunch of ca-cert related files that have dates of 2017 and 2020 respectively... and keeping in mind that I just now did a fresh re-install, it does beg the question why antique bundles are shipping in the current product.  (and yes - I also tried overwriting all of them with the latest working ones, which didn't fix anything)


Anyone got any ideas?

After today's huge Microsoft Windows patch update, this issue is now occurring on my other machine (Windows 10) as well...
