I am facing a problem and I believe that my localhost port may be the main issue.
First of all, I am trying to connect my QGIS with these links of WMS (http://localhost:8080/geoserver/ows?service=WMS&version=1.3.0&request=GetCapabilities&) and WFS (http://localhost:8080/geoserver/ows?service=WFS&acceptversions=2.0.0&request=GetCapabilities&) services.
However, at my PC the connection fails, referring me that the connection is refused.
I think that the GeoServer service which I have installed two day ago, might be the main problem. I connected it with localhost:8080, reserving this port close. As a result, the links of the services can't connect.
I tried to uninstall GeoServer, reinstalling it using a different port (1234), but the problem wasn't resolved. I think that the 8080 port is still reserved from the first installation.
Also, I have requested the services in another PC, using QGIS, and the services worked fine. Does anyone know how to resolve this problem?
