[No peer Connected]

I installed the same version of resilio-sync on two fedora workstations following this page:

https://help.resilio.com/hc/en-us/articles/206178924-Installing-Sync-package-on-Linux

When I connect these two computers on a standard directory, they are not connected to each others "no peer online -- 0 of 0".

In fact I can see a warning message in the Web UI configuration page : "Connection settings overwritten by config".

I don't know what this message means.

My configuration file loaded by the rslsync is located in ~/.config/resilio-sync/config.json and its content looks like:

{
    "storage_path" : "~/.config/resilio-sync/storage",
    "pid_file" : "~/.config/resilio-sync/sync.pid",

    "webui" :
    {
        "force_https": true,
        "listen" : "127.0.0.1:8888"
    }

I checked the troubleshooting procedure: my connection allow TCP and UDP packets, .... and I can't find out what the problem could be.

Note that I have been using Resilio since 3 years without any problem.
