I need help in solving some Checkup issues.

An unexpected error occurred. See your browser's console for more detailsUnable to create, retrieve, or remove encrypted credentials from the server. This is most commonly caused by a mismatch between the value of the blockPath value configured in cryptpad/config/config.js and the corresponding settings in your reverse proxy's configuration file, but it can also be explained by a websocket error. Changes to cryptpad/config/config.js will require a server restart in order for /api/config to be updated.

Console:

https://sub.domain.tld/block/O2/O2someencodedstring
404 Not Found
Can't read login block XHR_ERROR

https://sub.domain.tld/sheet/inner.html was served with incorrect Content-Security-Policy headers.

A value of "'self' blob: https://sub.domain.tld https:// sandbox.domain.tld wss://sub.domain.tld" was expected for the connect-src directive. This rule restricts which URLs can be loaded by scripts. Overly permissive settings can allow users to be tracking using external resources, while overly restrictive settings may block pages from loading entirely.

A placeholder file was expected to be available at https://sub.domain.tld/blob/placeholder.txt, but it was not found. This commonly indicates a mismatch between the API server's blobPath value and the path that the webserver or reverse proxy is attempting to serve. This misconfiguration will cause errors with uploaded files and CryptPad's office editors (sheet, presentation, document).

Content served from the /blob/ directory is expected to have a X-Content-Type-Options header with a value of nosniff.

Content served from the /block/ directory is expected to have a X-Content-Type-Options header with a value of nosniff.

Thank you.
