Hi,

Sorry to hear of your trouble. Some things to check out:

1. Are there any operating system updates still pending installation? Try rebooting the computer.
2. Is there a proxy server being used? Are you on a corporate or educational network? Can you try logging into another network e.g. Starbuck's, public library?
3. Could your antivirus or firewall be preventing us from connecting? Try disabling and launch Fusion to see if it helps.

Hi, I've been facing the same problem since the last couple of months. Please help me!

Hi @Anonymous,

I think the issue is that you are using a version of Fusion that is from June of 2016. Not too sure why it failed to update, but I believe this is why you may be seeing this issue. Can you please do the following to resolve the issue:

• Download and install the Clean Uninstall Utility here
• Run it
  • Hit NO when it asks you to clear the cache
• Install Fusion from this link here

Does everything work after reinstalling?

Thanks,

Hello,

I am facing the same problem "Unable to connect to internet Please check your network ......"

Please help me with the procedure to solve this problem.

Hi,

Sorry to hear of the trouble.  Was it working before and now not?

Here are some things to check out:

• Using Explorer rename the folder Web Services and relaunching Fusion.  This can be found in c:\users\{username}\appdata\local\autodesk This will prompt for a login at launch.
• Check to see if any antivirus programs are running and may be blocking access.
• Check for firewall interference.
• Check for proxy server being used.
• Using Explorer find and check the file "hosts" to see if your network connection is being redirected.
• Have there been any operating system updates that might be blocking access?

Hope this helps.

I am getting the unable to connect message when I try to start Fuion 360. Here's some info:

I typically use FireFox on Windows 10.

Proxy and Firewall are both turned off.

I have used a public wifi and my phone as a mobile hotspot. Have not used my personal home internet yet.

There are no pending updates for my OS.

I do not see a loginstate file to edit.

I am not sure how to tell if my hosts file is redirecting my server.

I did uninstall and reinstall Fusion 360.

Hi,

From the logs it appears there is a proxy server being used.

To check your Hosts file use File Explorer and go to C:\Windows\System32\drivers\etc

Use Notepad to open. If there is redirection you can comment it out using the # character.

Hope this helps.

This is what my hosts file shows. I think it is good, but let me know what I need to do if it is wrong.

# Copyright (c) 1993-2009 Microsoft Corp.

# This file contains the mappings of IP addresses to host names. Each

# space.

Hi,

The Hosts file looks fine. If you suspect a proxy is being used check your environment variables for an entry similar to HTTP_PROXY. If there, remove it and see if it helps.

I would also look at what's being loaded at start up. Apps such as antivirus or firewalls can inhibit the connect and may require adding Fusion to their internal "whitelists".

Additionally there are tools that can show you your network traffic with the idea you could see what might be impacting Fusion. Fiddler is a tool that can give you insight into this.

I have similar problems: after a forced update to the personal licence: data panel shows no projects anymore, in "recent data" I can see my files but cannot load them into fusion 360. I deleted the loginstate.xml as suggested at

https://forums.autodesk.com/t5/fusion-360-design-validate/fusion-360-data-panel-and-a360-not-showing...

But afterwards fusion 360 mentioned: no internet connection though I DO HAVE a working connection.

This is all very frustrating (for days now), if Fusion choses users to work online preferrably, those problems should not pop up in my opinion (and I'm not alone apprarently..).

Any help would be very appreciated.

Also: I see my files at https://myhub.autodesk360.com (fortunately).

Apart from the (neccesary) reconnection with internet, is there a way to "manually" upload this files from myhub  into fusion 360,  so that I can use them again using the data panel ?

thanks.

Hi,

Sorry to hear of the trouble. Can you try the following:

Delete your browser cache - in Fusion go to Help > Support & Diagnostics > Clear cache data (this forces a restart of Fusion).

If this doesn't fix it:

1. Exit Fusion and launch File Explorer.
2. Go to c:\users\{username}\appdata\roaming\autodesk\neutron platform\options.
3. Delete or rename the NMachineSpecificOptions.xml file.
4. Go into the {alphanumericfoldername} folder.
5. Delete or rename NGlobalOptions.xml.
6. Launch Fusion.

Hope this helps.

[ddbacker]

thank you for the reply.

- in fusion, when i go to help, support and diagnostics,  i don't see a "clear cache" only "diagnostic log files" and "graphic diagnostics". See can't do that. any help ?

- the second suggestion: I changed the names of the 2 files,  it helped the first time I opened fusion 360.

so I closed fusion again (to be sure) and reopend it. The problem popped up again: no internet connection  (I DO have connection) and 1 new .xml files with the name you mentioned also reappeared...(NNglobaloptions.xml).

And after the second opening of fusion  I did  see also the "clear cache data" at help menu..

So I cleared the cache, deleted the file, reopened fusion and.. no internet connection ...

Third try, I also cleared browser cache (again), then cleared cache data, then closed fusion, then removed the always reappearing file NNglobaloptions.xml (the other file didn't reappear again) then started fusion again ...

no internet connection....

So what now ?

Never never had that kind of  problem with the older  version of fusion..sorry but frustrated; why do they make such an update...

thanks for some more suggestions.

[ddbacker]

hello,

maybe the 2 xml files you mentioned may help you with your diagnostics ?

I uploaded them..

working with win 8.1

 thanks

[ddbacker]

hello,

could this be an option:

- remove fuison 360 (i tried this already..)

- make another registration (is this possible (on the same computer), with an existing one ?)

- reinstalling fusiion 360, using the new registration..

( I guess I have to forget about the old designs then.. I can still download them from the 360 hub before this reinstalling thing..)

 thanks

Hi,

A few things:

1. Can you connect to your Fusion hub via a browser? 
2. I reviewed the XML files and there wasn't anything to indicate what the trouble is. Can you upload the file autodesk.webdeploy.streamer.log? This is located in c:\users\{username}\appdata\local\autodesk.
3. Another option to try is to create a new user using Control Panel. Make it a standard user, login to that user and see if Fusion installs/launches. If so, then there's something in the other user's policies preventing the connection.

Looking at things that can cause connection issues: antivirus/malware is blocking us, "Hosts" file is using a redirect, an environment variable is set (e.g. HTTP_PROXY), Smartscreen, or VPN locking us out.

On the update itself, there's nothing in it that would affect the connection so I'm wondering if anything has changed in your system recently?

Regards,

[ddbacker]

hello,

1 Yes i can connect with the fusion hub

2 I uploaded the file

3. norton internet security allows everything where autodesk is mentioned..

I did not change anything to my system,  as far as I remember (didn't use fusion for a year or so, afterwards I only had too change to personal use licence).

And the good news: fusion reconnected again to internet, don't ask me why, it just happened... it has a kind of a will..

There's still a small issue with my data panel: it's empty, I have to manually donload my projects from the hub into fusion 360, and all apart (apparently there's no way to download them all together..)

Let's hope it stays like this.

thanks for your help.

Hi,

Similar issues I'm afraid. Originally, Fusion 360 was working fine for me. Then I started to receive the following message "We are currently updating our services". Now it won't connect to the internet. I've installed and carried out a clean re-install numerous times. Any suggestions to resolve this issue is appreciated. My files are attached below. 

Thanks

Hi,

Sorry to hear of the trouble. Can you try the following:

1. Using File Explorer go to c:\users\{username}\appdata\local\autodesk
2. If exists, delete the folder Web Services.
3. Exit and launch Fusion. This should take you to the login screen.

Hi Kevin, 

Thank you for your response. I deleted this folder as you requested. Unfortunately, I still cannot access Fusion 360 as I'm getting connection issue prompts (see attached). If you need me to edit other files just let me know.

Thanks,

Ronan

Hi,

Sorry to hear it's still an issue.

What kind of network is this? Home? Office? School?

There are several things that can cause this issue:

• Pending operating system updates. Reboot the system to ensure any pending updates are installed.
• Your antivirus software or firewall is blocking our access.
• Windows 10 - Defender's Smartscreen can also block us.
• UAC settings are too restrictive.
• Your Hosts file is redirecting your access through a server e.g. proxy server

Also, is it only Fusion that can't connect? Can you access the internet via the browser?
