Homeserver cannot reach the bridge. You probably need to adjust your configuration

I am trying to install matrix-appservice-slack at a NAS server to be used with synapse. Synapse is going very well, but matrix-appservice-slack Bring me this error:

The ports and all applications are open. I tested it with several tools but I cannot manage to make the bridge to speak to the server. I tried all the troubleshooting methods that I could find so far I double checked every yaml file I have and they are definitely clean. It says to me that the bridge is not connecting to the homeserver, but the thing is that there is no reason for explained. I had an error similar to this, but even after I fixed the likely error the problem persisted.

All apps are running, but they don't talk to each other.Could someone suggest to me where I can find the wrong configuration?
