According to this post Web Edition - using non-standard HTTPS port the duplicacy web UI uses LE with HTTP challenge.
Questions:
- It is possible to provision my own certificates instead?
- Where should they be placed? /config/certs?
- In what format?
- Will duplicacy notice if the files there have updated and relaunch web server on its own or do I have to do it manually?
- How can I prevent it from trying to talk to LE?
