I am able to access rest api on the main site, but not on the subsites. WPMU is running on IIS.
I'm sure it's likely the web.config but I have also checked WP Cerber and WP Rocket (explicitly not caching wp-json) to be sure and these don't seem to be causing the issue. I am getting a 404 trying to access it on all subsites.
Below is my webconfig. Any assistance is appreciated 🙂
