Error:

Unable to read key from file file://C:\xampp\htdocs\myhospitalnow\mhn-doctors-ms\storage\oauth-private.key

Sulotion:

1. Verify the File Path:

• Ensure that the file path in the error message is correct and that the file exists at the specified location.
• The path provided in the error message is:

C:\xampp\htdocs\myhospitalnow\mhn-doctors-ms\storage\oauth-private.key

2. Check File Permissions:

• Ensure that the file has the correct permissions, allowing the web server or PHP process to read it.
• On Windows, right-click the file, go to “Properties,” and ensure that the “Read-only” attribute is not selected. Also, make sure the user running the PHP process has permission to read the file.

3. Check the Key File Format:

• Open the oauth-private.key file and verify that it is correctly formatted.
• The file should start with -----BEGIN PRIVATE KEY----- and end with -----END PRIVATE KEY-----.
• If the file is missing or corrupted, you can regenerate it.

4. Regenerate the Key Files:

If the key files are missing or corrupted, you can regenerate them using Laravel Passport by running the following Artisan command:

php artisan key:generate 

• This will generate new oauth-private.key and oauth-public.key files in the storage directory.

5. Update the .env File (If Required):

• Ensure that your .env file correctly points to the key files. The paths should be relative to the base path of your Laravel project.
• Example:

PASSPORT_PRIVATE_KEY="file://C:/xampp/htdocs/myhospitalnow/mhn-doctors-ms/storage/oauth-private.key"
PASSPORT_PUBLIC_KEY="file://C:/xampp/htdocs/myhospitalnow/mhn-doctors-ms/storage/oauth-public.key"

6. Check for Any Path Issues in the Code:

If you are programmatically accessing the key file, ensure that the path is correctly specified in your code.

7. Restart the Web Server:

After making the above changes, restart your web server (Apache, Nginx, etc.) to ensure all configurations are reloaded.

8. Clear the Cache:

• Sometimes, Laravel’s cached configuration might cause issues. Clear the cache using:

php artisan config:cache
php artisan route:cache
php artisan view:clear
php artisan cache:clear
