I can't log in online after the update.

ytka1488 — Tue, 02 Jun 2026 06:13:06 GMT

Good afternoon. I updated fusion as standard and after that it won't let me into online mode, the diagnostic tools say that there is no response from one of the addresses. https://api.aps.autodesk.com/health

During manual verification on my part, there is a connection to the server, DNS and TCP/443 are working, but endpoint returns 403 Forbidden:

curl.exe -I -L --connect-timeout 10 --max-time 20 https://api.aps.autodesk.com/health
Result:

HTTP/1.1 403 Forbidden
content-type: text/html; charset=UTF-8
via: 1.1 google
Also:

Test-NetConnection api.aps.autodesk.com -Port 443
Result:

RemoteAddress : 34.149.246.28
RemotePort : 443
TcpTestSucceeded : True

However, before the update, network diagnostics had access to all addresses.

I tried repair fusion but it didn't help.

I'm experiencing the same, but it's a 404 instead of a 403 for me

Did anyone succeeded with this?

No. I even wrote to Avtodesk's support. But they didn't say anything. They said they were working on the problem. But it's already been 2 weeks. There is still no answer

I received the same answer from Autodesk support. Literally:

— This might be happening due to a known issue, due to the introduction of a new endpoint (As I understand blocked https://api.aps.autodesk.com/health as stated in network diagnostic utility).

— There are multiple situations/errors/cases going on for these errors. I will end the chat and will transfer you case to Fusion team. They will contact you via email with further steps/updates. No ETA. But they will contact you.

I have no idea what it is. But after talking to the neural network and executing a few commands, they told me that this was not my problem.

Not my case either.

Thank you for suggestion but it doesn't seem to be my case directly, as far as I don't see any dnssec enabled between me and api.aps.autodesk.com. But the nature of the problem is somewhere here.

There is something funky going on with this. I resolved this by pointing my DNS servers manually to 1.1.1.1 (Cloudflare primary) and 8.8.8.8 (Google Primary). And what do you know? It worked as it did before the update. However, I do not want to leave it here. But it did get me up and running.

I already have that set up. But it didn't help=[

Manually setting DNS worked for me too.

Assuming you're on Windows:

1. Open your Network & Internet Settings

2. Click on "Properties" at the top

3. Click "Edit" on DNS server assignment

4. Change the drop down to manual

5. Turn on IPv4 and enter the following:

Preferred DNS: 1.1.1.1
DNS over HTTPS: On (automatic template)

6. For alternate DNS:

Alternate DNS: 8.8.8.8
DNS over HTTPS: On (automatic template)

7. Restart Fusion and (optionally) run a network diagnostic test from the fusion service utility.

I did it all. But it didn't work. Still an error in https://api.aps.autodesk.com/health

But the cloudflare program from the website has helped me so far. https://one.one.one.one/

in traffic and dns(udp) mode
you just need to turn off all vpn and other settings, if you have
