I used the method in README as in https://github.com/ONLYOFFICE/Docker-DocumentServer#generation-of-self-signed-certificates, and it turned out self signed certificate would cause a connection error ...

Hello @mr-xiangxu, add the enviroment USE_UNAUTHORIZED_STORAGE=true from here if you want use selfsignet certs.

@igwyd Thx!
