An unexpected error occurred while downloading and opening a document from A360

[maximJG5KB]

I don't know if this is related to a recent update but as of this morning, I am unable to open any models on my MacBook Pro.

I get the same error message ("An unexpected error occurred while downloading and opening a document from A360") whenever I try to open a model and sporadically even when not trying to open anything.

Things I have tried:

- working in Offline Mode 

- disconnecting my computer from the internet

- uninstalling Fusion360 using the uninstaller and reinstalling

None of these has helped the issue, I'm still seeing the error.

Also, whenever I try to quit Fusion360, it stalls and crashes.

I thought it might be server-side so I tried opening a file on a different machine running Windows without a hitch.

I can even create and save files on my mac, just not open them.

Following another thread from 2015 (old thread) , I also deleted/renamed BrowserStorage_login.dat.

I couldn't locate the PLM360Cache so I did not delete that.

Any suggestions? Please let me know what files I can upload to help look into the issue.
Thanks!

I've been having a similar problem since yesterday. "An unexpected error occurred while downloading....." on a Mac. For me, the problem began when I ran a script to duplicate a simple design 61 times with different parameters and Save As each to a cloud folder. It seemed to work well but had a problem uploading one of the files. I let it sit a while to try to finish uploading, but Fusion eventually crashed. I reopened Fusion and figured I would delete the 60 files that did actually make it to the cloud and start over, but when I tried to delete from the cloud, Fusion crashed. Next, I tried logging into A360 through via web browser and was able to successfully remove the files that way. Now, I can view my files in the Data Panel but can't download or upload anything and Fusion is, even more annoyingly, alerting me every two seconds about this error. I'm completely stuck. I tried logging into Fusion on a computer at work and my account seemed fine. Everything seemed to work normally on that computer. My guess is that Fusion on my personal computer it's still trying to upload and/or download files that don't exist. I hope someone can help me get to the bottom of this!

There is definitely something stuck in the upload queue. If you're not worried about the designs in the upload queue, could you give option 3 a try in the below link?

I think that will be the fastest way to resolve the issue. I hope that helps. Please let me know if you have any questions.

Hi Nathan,

I took a look at the networking stuff you mentioned and none of it seemed to apply (I got a secure connection, all ports open on router and computer, no proxies, no firewalls, nothing that could mess with the connection to the servers).

Out of curiosity, I decided to try out the advice you gave to trevordodd and everything seems to work fine now.

Knowing what the problem is, I can start to guess at what caused it. My best guess is that an upload got interrupted at a bad time by a spotty connection and/or a file that was open on multiple computers caused some sort of issue as one got saved/uploaded. Beyond that, your guess is as good as mine.

Thanks for the help!

Thanks, innovatenate. It looks like you got two of us up and running! After completing option 3 from above, things were better but I was still having issues deleting files from the cloud so I manually deleted (er, moved) the locally stored files in the neighboring folders. Everything seems happy now.

Link not available. can you update the link? I am having the same problem. This error occurs when opening the project. "an unexpected error occurred while downloading and opening a document". Reinstalling fusion360 did not help.

Exact same situation here.

I am getting really annoyed with Fusion. If you want to charge it like a professional program, please maintain it like a professional program
