SymmetricDS Sample - client node refused to connect to server node - database-connection

Question

I am working on the example from the SymmetricDS tutorial. I am using the configuration files corp-000.properties and store-001.properties found in the samples directory of the download zip. I have placed them in the engine directory and edited them so that corp-000 is using a Postgresql DB as master-000 and store-001 is using an MySQL DB as slave-001, both on separate machine.
Here are the config from corp-000.properties:
engine.name=master-000
db.driver=org.postgresql.Driver
db.url=jdbc:postgresql://127.0.0.1/master?stringtype=unspecified
I've also enable the firewall (8080/tcp and 5432/tcp) and changed port from 31415 to 8080: However when the same error still came out and the url returns this result:
This site can’t be reached
<Master-node-IP> refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
What should I do to solve thise problem?

Answer 1

Add to corp configuration
auto.registration=true
Can’t hurt to add
auto.reload=true
Solution by #swm is
The solution is need to set bind ip in symmetricDS

Answer 2

Below are some example configs.
What is happening here is that the main or master cannot see the sync / registration urls and ports not the database.
Make sure the following are setup correctly.
MAIN
registration.url=
sync.url=ttp://<IP>:<PORT>/sync/<SDS_MAIN>
CHILD
registration.url=http://<IP>:<PORT>/sync/<SDS_MAIN>
sync.url=http://<IP>:<PORT>/sync/<SDS_CHILD>
