Note: Carefully ensure there are no spaces or blanks within your certificate file, by selecting the entire text and looking for blank spaces on a text only editor.
2. Check Apache's configuration file to ensure the correct path is specified for the correct certificate file.
If the issue persists, reissue your certificate in your MySSL account.
