Cells Sync can't connect to Docker on the same machine

I would like to try Pydio Cell and the Sync client, so I installed it on a docker within my Windows machine.
The communication through the web interface is working very well.

When using the Pydio Sync Client, I have different issues:

  • Taking the default configuration (https://localhost:8080) I receive a message telling that my certificate is signed by an unknown authority (which is true, it is an auto-certificate).
  • When changing the configuration to disable the TLS certification, I receive a strange answer “No connection could be made because the target machine actively refused it” from the client.

Are there some options I missed, to connect Sync to the server?
As explained above, I can access the server through the web interface.

Any help is welcome as on this stage the tool that seemed promising is not usable for our needs.

PS: I’ve created another topic, but on the wrong part some time ago, without much luck. I hope that I will be more lucky here :yum:
