XAMPP apache cannot connect to listening port

I am using xampp on windows 10 and trying to get apache to work. I have set it to listen to port 50563 in the httpd.conf and httpd-ssl.conf, however when I run httpd.exe I get this message:

(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : AH00072: make_sock: could not bind to address [::]:8080

(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : AH00072: make_sock: could not bind to address 0.0.0.0:8080

AH00451: no listening sockets available, shutting down

AH00015: Unable to open logs

I have tried running as administrator, I check netstat and that port is free. What should I do?
