I can connect to other device when I use default Discovery server.
But I can get other device’s IPadress and can’t connect to him when I use my Discovery server.
I add other device and get his IP . But he have no any tips.
I don’t find any different in GUI between default Discovery server and my Discovery server.
The client presents its device certificate over the HTTPS connection, which the server then calculates the device ID from. This proves “ownership” of the device ID.
I don’t know about your problem as such, but the yellow device status means that no folders are shared with it, if I remember correctly. That means nothing syncs even if it does connect.
Do you have both devices configured to use your discovery server?
You could revert back and see over which ips they connect, and see if those are advertised via your server.
Otherwise, enable connections debugging facility, see the connections happen, and see why traffic cannot be router by using netcat or something like that.
