To resolve the issue, confirm or re-check the Dynamic Compression setting in the IIS Manager.

The Dynamic Compression option is a bottom-up design, which means that any website under IIS can enable it regardless of the IIS general setting. Therefore, it is needed to disable dynamic content compression inside the WebApp entity under IIS manager.

To check the option in the Apex Central server:

  1. Open IIS Manager and look for the tree in the left panel.
  2. Click and expand Sites.
  3. Click and expand Default Web Site or Virtual Site.
  4. Click WebApp and show the configuration window in the main panel.
  5. Look for "Compression" in the IIS section and double-click Open.
  6. Un-check the "Enable dynamic content compression" option.

    This should be able to disable the dynamic compression for the site (Apex Central).

  7. Click Apply in the right Action panel to disable the dynamic compression immediately.
  8. Test the SO List sync in Apex One.
