Currently trying to set up SDL server files to sync with local Oxygen customizations and configurations via the authoring bridge.

Configured the Web/Author/ASP/ClientConfig/SyncInfo.xml file to synchronize local directories with the Web/Author/ASP/ClientConfig/Oxygen folder, and the sync works fine for most files.

However, synchronization fails for the following files:
• Web/Author/ASP/ClientConfig/Oxygen/XXX_DITA/layouts/XXXLayout.layout
• Web/Author/ASP/ClientConfig/Oxygen/XXX_DITA/layouts/NewXXXLayout.layout
• Web/Author/ASP/ClientConfig/Oxygen/XXX_DITA/css/actions/readme.md
• Web/Author/ASP/ClientConfig/Oxygen/XXX_DITA/rules/styleguide.sch
• Web/Author/ASP/ClientConfig/Oxygen/xxx_dita.framework
• Web/Author/ASP/ClientConfig/Oxygen/xxx_dita_map.framework

Each of the sync failures come with a similar error message:

• “The synchronization of file 'https://WsBaseURL.sdlproducts.com/ISHCM/ClientConfig/Oxygen/XXX_DITA/layouts/XXXLayout.layout' to 'C:\Users\%USER PROFILE%\AppData\Local\SDL\InfoShare Client\123456789\Config\Oxygen\XXX_DITA\layouts\XXXLayout.layout' failed with error: Unable to reach the repository 'New account'. A connection with the service 'https://WsBaseURL.sdlproducts.com/ISHCM/ClientConfig/Oxygen/XXX_DITA/layouts/XXXLayout.layout' could not be established. The remote server returned an error: (404) Not Found.

Suspect this has to do with filetype restrictions on SDL's end. 

Add the file extensions that are not syncing correctly to the MIME Types Filter in the Internet Information Services (IIS) Manager.

1a. Open Internet Information Services (IIS) Manager.
1b.Click the server or website
1c. Double-click the  MIME Types Filter Icon.




2. In Actions pane, click Add:



3. Populate the File name extension and MIME type:
*Note - Two primary MIME types are important for the role of default types:

• text/plain is the default value for textual files. A textual file should be human-readable and must not contain binary data.
• application/octet-stream is the default value for all other cases. An unknown file type should use this type. Browsers pay a particular care when manipulating these files, attempting to safeguard the user to prevent dangerous behaviors.

4.  If previous attempt to sync resulted in a "synced with errors" message

• remove and re-add the account from the client tools on the local machine
• delete the accounts on the local machine from:
  • C:\Users\%USER PROFILE%\Documents\SDL\InfoShare\
  • C:\Users\%USER PROFILE%\AppData\Local\SDL\InfoShare Client\

IIS MIME Type Filtering: If a specific file extensions MIME Type is not listed/identified, it returns a 404 error.
