Could you please give us more details about the BitNami stack you are using, version and platform, please? Besides, I think I do not understand if you have any other problem in addition to the log you posted.
Also, the errors shown above are related to the certificate shipped with the stack, that is set to a generic domain (www.example.com) to allow HTTPS access without anymore configuration. This generic name is not matching with your hostname, but this is normal and you do not have to worry about it. You can avoid receiving these errors in logs by changing the certificate for one signed to your domain name.
I hope that this helps you. Regards.
