Hi,

The error message "Failed to read private key: Error 101077092" suggests that there is an issue with reading the private key file for your SSL certificate. To fix this, you can try the following steps:

1. Double-check the path and filename of the private key file you provided. Make sure the file exists in the specified location (C:\Program Files\MATLAB\MATLAB Web App Server\R2022b\bin\win64\).
2. Verify that the file format of the private key matches the expected format for SSL certificates. Common formats include PEM and PFX. Ensure that the file extension matches the format and that the contents of the file are valid.
3. Confirm that the private key file has the appropriate file permissions. Ensure that the user running the MATLAB Web App Server has read access to the file.
4. If the private key file is password-protected, make sure you have provided the correct password in the server configuration.
5. If you obtained the SSL certificate from a certificate authority, ensure that you have both the private key file and the corresponding certificate file. The private key and certificate should be properly paired.
6. If you have the certificate in a different format or suspect any issues with the private key file, try regenerating the private key and certificate files from the certificate authority and ensure they are in the correct format.

If you've verified the above steps and the issue persists, it may be helpful to consult the MATLAB Web App Server documentation or reach out to MathWorks support for further assistance, as they will have more specific knowledge about the server and any potential troubleshooting steps.

The password for the private key was the problem.

I fixed it.

Thanks for your answer!
