Heroku: ERR_TOO_MANY_REDIRECTS - spring-boot

Question

I have a java project with spring boot and spring security that I deployed to Heroku, but when I tried to access a simple endpoint to test, typing the url in chrome address bar, I received ERR_TOO_MANY_REDIRECTS.
URL I tried to access:
https://myapp.herokuapp.com/public/ping-pong/ping/ping
endpoint:
#RestController
#RequestMapping(value = "/public/ping-pong")
public class PingPongController
{
#RequestMapping(value = "/ping/{ping}", method = RequestMethod.GET)
public ResponseEntity<String> ping(#PathVariable("ping") final String ping)
{
try
{
String resp = "What?";
if (ping.equals("ping"))
{
resp = "pong";
}
return new ResponseEntity<>(resp, HttpStatus.OK);
}
catch (final Exception e)
{
System.err.println(e.getMessage());
return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
}

This endpoint is working very well locally, so I think the problem could be some configuration on Heroku.
Can anyone help me?
