We already tried restart the service and increase Maximum heap size from 2GB to 4GB but nothing works (Note: our cloud spec 8GB of memory)*
Can you reach the server using CLI ? (telnet API_gateway_server_ip port)
Check out this post: API Gateway 9.12 Not Working
i already checked the conf files and port is pointing correctly to IS and data store. Any other solutions?
Please check if below KB article solution works for you.
This error occurs if the Integration Server (IS) is not running on port 5555.
The problem is that the installer is not passing the IS port information to API Gateway.
There are two proposed solutions for the issue above, either of which can be used.
Solution 1: Create the port 5555 and provide the necessary “allow” access to the port.
Solution 2: Change the default port of IS in the following properties file and restart the IS.
SAG_HOME\profiles\IS_default\apigateway\config\uiconfiguration.properties
Thanks,
