Thanks for using Bitnami. Can you give us more information about your issue? Which application are you using and in which platform? Is it an installer, a cloud image (AWS, GCE, Azure, other) or a virtual machine?
Also note that if you generate your custom self-signed SSL certificate it won't be trusted by your browser because it is not signed by any certificate authority (that is, a trusted company such as Let's Encrypt or others). We have a tool that will help you to generate and configure a free Let's Encrypt certificate. You can get more information about this tool in the link below
Apart from the above, we have a Support Tool that will gather relevant information for us to analyze your configuration and logs. Could you please download and execute it on the machine where the stack is running by following the steps described in the guide below?
