Oops, everybody! When I try a simple openConnection (code below has been simplified to demonstrate):
URL url = new URL("url aqui");
url.openConnection();
I get the error:
java.lang.RuntimeException: java.net.ConnectException: Connection refused (Connection refused)
I just turn off the CSF which gets everything normal. I've already tried using CSF with the default setting, and nothing is solved. The site I can access normally.
If it matters, I'm using tomcat 9 and csf v12.08.
I have tried various configurations in CSF and so far nothing. Does anyone know anything about it so I can try?
