Seafile on BPI M64 with https and web interface

Hey, i want to install a seafile server on my banana pi M64 which also includes an encryption and a web interface through seahub. I tried several images like linux ubuntu and debian and the installation always went well except for the part with the encryption and the web interface. Does someone have some experiences with seafile on a M64 or even have a solution that could work?

Thanks and many greetings omatate
