AUSST Failed to download FFC XML

[witsu89169935]

This is on a new AUSST instance, Windows Server 2022, IIS.

Running  AdobeUpdateServerSetupTool.exe --root="C:\inetpub\wwwroot\updates" --fresh --filterProducts="APRO,AEFT,FLPR,AUDT,KBRG,CHAR,ESHR,DRWV,ILST,AICY,AICY,IDSN,LRCC,AME,PHSP,PPRO,SPRK"

After 20 or so minutes it'll fail with the below in the log file. I've also tried without the product filters and get the same result. Trying th eoperation with JUST --acrobatonly seems to succeed, so I suspect it's one of the other products causing problems.

How do I address this? I've tried the operation on three different ISPs to the same result.

Hi @witsu89169935,

Thank you for reaching out. Based on your query, it appears that you are encountering issues while downloading updates using AUSST. Please confirm if this is the issue you require assistance with.

To begin troubleshooting, we recommend reviewing the following guide which outlines common AUSST issues and solutions:
https://adobe.ly/4i2YTup

From the log you shared, the error suggests that AUSST is failing to download a required FFC (Feature Functionality Configuration) file. This failure is commonly caused by:

Network instability or restricted access to Adobe endpoints.

Permissions or timeout issues with IIS

Local firewall or proxy restrictions

Please ensure that the server has unrestricted access to all required Adobe endpoints. Refer to this documentation for a full list of necessary domains and network configurations:
https://adobe.ly/3FYvMet

Additionally, confirm the following:

• There is sufficient disk space on the system (we recommend at least 50–100 GB)

• IIS has the appropriate write permissions for the directory at C:\inetpub\wwwroot\updates

• Antivirus or endpoint protection software is not interfering with the download process

• There are no HTTP errors or timeouts recorded in your IIS logs

After verifying the above, rerun the AUSST command using:

AdobeUpdateServerSetupTool --root="C:\inetpub\wwwroot\updates" --fresh

Hope this helps. Please let us know if the issue persists after these steps, and we would be happy to assist you further.

Regards,
^AN

[witsu89169935]

• There is sufficient space (600GB free)
• IIS_USR has modify (write) permissions on the directory
• AV was put in bypss mode for testing
• IIS logs do not show any errors

Re-running the command with --fresh and no filter options results in the same error.

Hi @witsu89169935,

Thank you for your response and for the detailed logs.

As a next step in troubleshooting, please ensure that your web server is running correctly. A misconfigured or non-functional web server can prevent AUSST from downloading updates successfully. You can verify your internal update server by following the steps outlined in the official Adobe guide here:
Verify your internal update server

Additionally, confirm that your server has unrestricted access to all necessary Adobe domains. Any firewall, proxy, or DNS-related restrictions can interrupt the update process. Please refer to the Adobe network requirements provided in the earlier message for the complete list of required endpoints.

It's also possible that a previous failed attempt may have resulted in a corrupted local cache. I recommend manually deleting all contents from the following directory before re-running the tool with the --fresh option:

C:\inetpub\wwwroot\updates

Once these steps are completed, please attempt the AUSST sync again. If the issue persists, feel free to share the updated logs, and we’ll be happy to assist you further.

Regards,

^AN

I've been unsuccessful at running Fresh or Incremental without the product filter string. It seems it fails on the "APRO" product. I was able to add products to the download string one at a time until I had everything. Oddly enough I can run a separate task with --acrobatonly which is successful most of the time.

[Anshul_Nautiyal]

Hi @witsu89169935,

Thank you for confirming the details. Since you’ve already tested across multiple ISPs and configurations, and have gone through the recommended troubleshooting steps, I would recommend opening a support case with Adobe for further assistance:
https://adobe.ly/44oLt8R

Let us know if you need further assistance.

Regards,
^AN

[bryantd47328835]

I am also experiencing the same issue in our environment and have also opened a support case with Adobe.

[Bani Verma]

Hi there, 

Since you have already opened a case with our support team, I am assuming you have already tried all the troubleshooting steps shared above in this thread.

I would suggest that you wait for their reply. They can take a screen share, check for the root cause, and help you resolve it. 

Thanks,
^BS

[Michael288643977wq3]

Hi guys

Is there any news on this? We are experiencing the exact same issues.

I updated to the latest AUSST-EXE and attempted a new sync, but I am receiving the same errors.

We did not experience any issues with the download until February, and the server configuration has remained the same since then.
It seems to be more of a general problem with Adobe?

[Bani Verma]

Hi there, 

Sorry to hear that you are having trouble deploying updates using AUSST. Could you please try the troubleshooting steps shared in the following help document and see if that works: https://adobe.ly/3TfJjSt.

If it still fails, could you please share the following logs with us, located in the %temp%  folder in Windows and the ~/Library/Logs folder in macOS:

• AdobeUpdateServerSetupTool.log
• AdobeAcrobatUpdateServerSetupTool.log

DLM.log is located in the following locations:

• Windows: 
  • %Temp%\CreativeCloud\ACC\AdobeDownload
  • %Temp%\AdobeDownload\

I hope this helps you.

Thanks,
^BS

[Michael288643977wq3]

Hi Bani

As mentioned, the download was working at the end of January (see attachment), and we have not changed anything in the server configuration.

Nevertheless, I have now looked through the troubleshooting tips and also tried a --fresh download. I still have the errors.

The requested log files are in the attachment. I am currently checking with our internal security department to see if something is being blocked, but nothing has been changed. Or have Adobe's target URLs changed?

[Bani Verma]

Thank you for sharing this. Give us some time to review the logs, and we will get back to you soon.

^BS

[Michael288643977wq3]

Thank you. Btw, here is our FilterConfig.xml which we use to download.

[Michael288643977wq3]

For your information, I have now opened an Adobe case anyway: E-001705017

[Anshul_Nautiyal]

Hi @witsu89169935,

Thank you for sharing the logs and informing us that the case has been raised.

After analyzing the provided log file, we’ve identified a few blockers that are preventing the successful execution of the Adobe Update Server Setup Tool (AUSST). Please review the following recommendations:

Ensure the machine has stable internet access without interruptions.

If your environment uses a proxy server, confirm that proxy settings are correctly configured both at the system level and within AUSST.

Confirm that ports 80 and 443 are open and unrestricted.

Ensure that access to Adobe domains is allowed. Refer to this document for a complete list of required domains:
https://adobe.ly/4kEBwJP

Try running AUSST from a non-restricted internet connection to rule out network-level restrictions.

Security Software
Temporarily disable antivirus or firewall to check for interference with CDN or download activity.

Some endpoint protection tools may block or delay access to Adobe’s content delivery network.

Drive & Permission Checks
Ensure that Drive D: has sufficient free space.

Verify that the user running AUSST has full read/write permissions for:

D:\updates\2025

D:\config\2025\FilterConfig_2025.xml

If permission issues persist, temporarily configure AUSST to use an alternate folder or drive to isolate the cause.

SSL Inspection
If your organization uses SSL inspection or deep packet inspection, it may interfere with Adobe CDN communication.

Please add Adobe CDN domains to the SSL bypass list to ensure seamless connectivity.

Hope this helps. Let us know if you need further assistance. 

Regards,
^AN

From what I was able to find out so far, it seems to be related to issues in the Amazon CloudFront CDN. Servers happily serve the icons.xml, but refuse to answer queries for the ffc.xml. This is *not* a client side issue

[Michael288643977wq3]

For everyone affected, try the following, which worked for me after a lot of trial and error. Make sure you have version 6.2.0.3 of AUSST-EXE and restart the server immediately before attempting to download.

Adobe Engineering is still working on my case, but not very satisfactorily quickly.

[Anshul_Nautiyal]

Hi @witsu89169935,

Thanks for sharing your workaround — we really appreciate you taking the time to post it.

Please note that our engineering team is actively working on this issue and will assist you in getting it fully resolved as soon as possible. Let us know if you experience any further issues in the meantime

Regards,
^AN

[johny57408966]

I am experiencing the same issues.  Only have the latest 6.3.0.1.  Can you post the 6.2.0.3 version?

[Michael288643977wq3]

I hope this works for you:  AUSST_6_2_0_3 (1).zip

[johny57408966]

I still feel it is an issue on the source side because I was able to download initially using 6.3.  Having said that, althought I had the same issue with 6.2.0.3, I got further along after multiple tries and I am now set.  I have run incremental and cleanup for the last 2 days and no issues.

Thanks for your help! 

[exavior-nf]

Have the same issue, decided to try older version but it's unavailiable, can you reupload it?

[Michael288643977wq3]

AUSST_6_2_0_3 (1).zip

[Michael288643977wq3]

According to our Adobe case the problem should now be solved:

Hi Michael,

Greetings.

I hope this email finds you well.

I wanted to let you know that the engineering team has resolved the issue from the backend, and you should no longer have any problems with the AUSST server.
