"No internet connection" when on mobile hotspot

[PeterMoll]

I have this weird problem since a couple of months that when I am connected to the internet through my mobile hotspot, Fusion says it is not connected to the internet. Browsing works fine, so there definitely is a working connection. I also ran the network diagnostic test from the Fusion service utility and everything seems fine there, but Fusion remains in offline mode till I connect to a wifi network, then gets back online without a problem...

(See screenshot)

Also this used to work without any problems till a couple of months ago.

Can someone help me to debug this please?

Thanks in advance, Peter

Fusion might be confused by the hotspot. Can you see if this recent knowledge article helps?

@PeterMoll Can you also please collect the logs file in this state? 

Refer to this article on how to launch the Fusion service utility (based on if you are on Mac or Windows) and the Gather system info is what we will need. If you can attach the generated zip files here that will help. https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How...

1. Run Fusion using hotspot

2. Launch Fusion service utility

3. gather system info

@Phil.E, I'm a bit wary of following the knowledge article ( repairing or reinstalling Fusion ) as I am not sure if I will lose any settings that way.

@RajkumarIlanchelianI attached the zip files, thanks for looking into this. BTW using my hotspot to post this, so internet connection is fine, just if you wanted to know...

@PeterMoll Thank you for the logs. We are having our engineering team look at it to see what could be happening.

@Rajkumar.ilanchelian , any chance there is any news on this? Some places I work my hotspot is the only connection...

Thanks, Peter Moll

[PeterMoll]

@RajkumarIlanchelian, @Phil.E , is there any news yet on this issue?

I just did a clean install on my sons laptop where Fusion never has been installed on and exactly the same problem. I also contacted support about this, but also posting here...

After some more researching the issue, also with help from Autodesk support, it finally turned out to be a setting on my phone; I changed the APN protocol setting from IPv4/IPv6 to IPv4 only and now Fusion is not complaining anymore about no internet. Not sure if this is a bug though...

@PeterMoll Glad to know that you got this working. Will check with the teams here to see if this is a limitation or if this is an issue. Thank you.

Fusion in 2025 is still having this issue. Please look into it as it’s quite a mess not to be able to work when I’m out and about. 

[RajkumarIlanchelian]

@medha_shaji Can you add details on what kind of issues you are talking about?

Started having this issue today. I've been primarily dependant on mobile hotspot and it's been spotty sometimes but mostly works. Since yesterday, however, it won't go online. If I manually swtich to offline mode then switch back to online I'm stuck at "Going online.. Establishing connection" but then it fails to connect. I'm sending this message using the same hotspot where this is happening right now. As far as I'm aware my phone hasn't updated and I haven't messed with any settings since it last worked on Thursday. Let me know if you need me to send any diagnostics.

There was an AWS outage this morning that impacted Fusion along with most of the internet. That started late last night but is mostly resolved as of this morning. Are you able to connect now? If not: launch Fusion, collect diagnostic log files, create a new thread and tag me.

I can confirm it's working now. It may have indeed been related to the outage. Thank you.
