Bug: Client certificate file not working

[Daniel-CS-Team]

Actual behavior

When trying to configure a sync server requiring mTLS authentication, I can upload the client certificate, but it is not shown in the GUI nor used by MISP for the connection resulting in an Error: Error: Connection test failed. Reason: curl error 92 'Stream error in the HTTP/2 framing layer': HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)

Expected behavior

After uploading the client certificate file, it should show in the GUI and be used for the connection.

Steps to reproduce

Create MISP-Instance requiring mTLS authentication. Create second MISP-Instance to sync with first and try to upload appropriate client certificate. When checking the file-system, the certificate is stored there correctly under /var/www/MISP/app/files/certs/ 1_client.pem. Permissions are correct as well. Test the connection and observe the error
