Workaround
- Use a feature service URL referencing the port 6443 instead of the web adaptor.
- Disable HTTP/2 on the Internet Information Services (IIS) website hosting the GIS Server's web adaptor.
- Use Firefox as the browser, or disable http/2 on Chrome/Edge, but this requires everyone in the organization to be using the same browser and/or settings.
