CoreSync.exe using all bandwidth

I recently started a new Creative Cloud account after having another one set up on this computer (Windows 10).  Ever since then, I have been noticing massive connectivity issues across our whole network.  Upon looking at Resource Monitor, I have come to see that CoreSync.exe is constantly uploading data.  From within the Creative Cloud App, pausing sync restores internet service to the rest of my network.

When I right-click the CC icon in the notification area, it always says "0.57% of 100GB," never increasing.  Actually, my Creative Cloud folder is only 3.75 GB in size.

It may also be noteworthy that the the folder location that I use for syncing is C:\Users\admin\Creative Cloud Files.. but when I go to the Creative Cloud Preferences within the app, it gives me C:\Users

admin.

Windows 10 Home

Creative Cloud 4.5.0.331

Creative Cloud Sync 2.4.6.82

This issue eventually resolved itself after the Cloud folder finished syncing.  It took about a week to sync the 4GB folder, but once it finished, our network speeds returned to normal.

Hi,

Thanks for reporting the issue.

Would you be able to collect and upload log files from your system?

Here is a link to an article about the tool with a link to download it.

Log Collector Tool

The tool will create a zip file on the desktop of all the log files. Please could you send us your logs (punaggar@adobe.com) using the tool.

Engineering may have some additional questions but this will help us get started.

Thanks,

Puneet Aggarwal

I went through the steps listed at that link, and each step seemed to pass without issue.  I didn't see anything at that link that referenced "AutoProxy" however.

Hi Matthew,

The link does contain some heads about proxy servers and firewall settings. Could you please try them, if not tried earlier.

Thanks,

Puneet Aggarwal

In the link you gave, CTRL+F shows three uses of the word "proxy"

The instructions say "Disable authentication proxy servers. If your computer is behind an authorization proxy server, disable it. For instructions, consult your network administrator or your proxy server documentation." and " Check firewall settings.  If your computer is behind a firewall, make sure that the firewall is not blocking the activation server through ports 80 and 443.  For instructions on allowing access to the activation server, consult your network administrator or your home network’s firewall documentation. Note: If your firewall requires an executable, specify PDApp.exe, located here: Windows: Program Files\Common Files\Adobe\OOBE\PDApp\core"

1. I checked internet options in Internet Explorer. Connections-> LAN Settings-> Proxy Server box is UNchecked.  We do not use a proxy server on this network.

2. Both ports 80 and 443 are open. In internet explorer, I tested http://www.microsoft.com:80/  and https://www.microsoft.com:443

and they both go through with no problem.

3. My PC uses Windows Defender by default. I do not know how to check if my firewall requires an executable.
