SSL Installation Help on Pwndrop Domain

I am having trouble installing SSL on my domain before setting up Pwndrop. When I attempt this, the Pwndrop service becomes inaccessible. If I install Pwndrop first and then try to add SSL, I face multiple issues with SSL certificate issuance on the domain. I need an expert who can troubleshoot this for me and provide a step-by-step guide on how to resolve these issues during a fresh setup.

Key Requirements:
- Expertise in SSL installation and troubleshooting
- Experience with Pwndrop
- Strong knowledge of Apache servers
- Proficient in command line operations
- Ability to provide clear, understandable guidance
