Connection refused when using IP but not when using localhost

I have deployed my web application in my apache 9 server. I have configured the server following internet guides, and it works fine if I use this link:

http://localhost:8080/ejercicios-programacion/

which redirects me to

https://localhost:8443/ejercicios-programacion/

However, if I try to do the same but not using localhost but the IP, for example:

http://xx.xxxx.xxxx.xx:8080/ejercicios-programacion/

it still redirects me to

https://xx.xxxx.xxx.xx:8443/ejercicios-programacion/

but I get a "refused to connect" error.

Up until today it was working perfectly both ways, and the only thing I changed was adding ssl security to my webpage, so it most likely has to do with that. Here are my connectors in servers.xml:

<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

<Connector port="8443" URIEncoding="UTF-8" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="C:/cert.pfx" keystorePass="defaultpassword" />

Does anybody know why this is happening?
