REST API Connection failed

Hi M-Files fellows

I am facing a problem with the REST API call on a specific environment with a proxy server. So we have a public domain with an ssl certificate, using port 443 and a separate  internal m-files app server.

M-Files Web and RPC over http works fine, so the login is possible with the web browser as well as with the desktop client. However, using the REST API call it doesn't work.

I use a module on make.com, which works perfectly with other environments, but on this one I get a time out and checking the windows logs on the proxy server I find this error message:

M-Files: 23.10.13060.5

Due to a user or client operation, an error response with the following reference ID was sent to the client: 

9b1f3b0a-fdb0-4e29-8662-ba2cc5de3894

If the error requires further investigation, see below for detailed error information.

Does anyone know or assume what could be potential errors according to this message?
