Hello, here is thing: Ports that open by Syncthing, not responding, here is details: I have exact behavior on 2 servers. Connections between 2 apps. establishing over proxy , but suppose to be directly.
Virtual server with ephemeral External IP address: 188.8.131.52 (AWS cloud, non routable internal IP address assigned, an External IP NOT assigned to the host)
Local IP Ethernet: IPv4 Address. . . . . . . . . . . : 184.108.40.206 Subnet Mask . . . . . . . . . . . : 255.255.240.0 Default Gateway . . . . . . . . . : 220.127.116.11
Applicaton started and open ports, as usual: TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING 1988 TCP 0.0.0.0:8384 0.0.0.0:0 LISTENING 1036 TCP 0.0.0.0:22000 0.0.0.0:0 LISTENING 1036
I added RDP 3389, to show that all configuration correct. All permission, firewall and routing set correctly. Inbound traffic restricted completely, only HTTP\S ports allowed. 2 trusted networks completely open, where sync appl. active
I’m able to establish connection to RDP port. I’m NOT able to establish connection to Syncthink application.
