Error accessing REST API

    The Instant Images plugin reports a red warning bar:

    There was an error accessing the WP REST API.
    Instant Images requires access to the WP REST API via POST request to fetch and upload images to your media library.

    I asked my web host for assistance and this was their response:

    I was able to replicate the error message, however as far as I can tell, the issue is a 404 rather than the request being blocked:

There are only two POST requsts and the only one which apparently errors is the first which looks like the plugin attempting a test.
85.92.65.92 - - [05/Apr/2022:18:36:14 +0100] "POST /wp-json/instant-images/test/ HTTP/1.1" 404 105 "[My Domain]/wp-admin/upload.php?page=instant-images" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:98.0) Gecko/20100101 Firefox/98.0"
85.92.65.92 - - [05/Apr/2022:18:38:14 +0100] "POST /wp-admin/admin-ajax.php HTTP/1.1" 200 51 "[My Domain]/wp-admin/upload.php?page=instant-images" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:98.0) Gecko/20100101 Firefox/98.0"

If this were a block, a 403 would be expected rather than a 404 which suggests that the API is not correctly configured to respond to the request.

I can see at the link below a similar issue discussed by the plugin developer who made an error when pushing an update to the plugin. His suggestion was to uninstall and then re-install the plugin completely.

If this does not resolve the issue I would advise showing the above to the plugin developer for their input as this isn't a case of the API being blocked as far as I can tell.

    I have tried uninstalling and re-installing the plugin, but the error remains.
    This means that the plugin fails to download and resize images to add to the media library.

    Grateful if you can assist, as it’s a really fabulous plugin to have (thank you!)

    @alanthompson64 Do you have any security plugins running that would be blocking the REST API? It’s also possible you have a server rule blocking access to the API.

    I have tried uninstalling and re-installing the plugin, but the error remains.

    That wouldn’t solve this issue. Something on your server is blocking the REST API.

    Solved – I have a caching plugin called Swift Performance, which also has a “plugin organiser” that allows access rules to be created for plugins, to avoid bloat where they are not needed.
    At some point, I must have added Instant Images to this, to block Front-End access (thinking the plugin is only needed on the back-end).
    However, removing this rule has fixed the issue.

    thank you
