Why can't I connect to any of the Web Map Services (WMS/WMTS/WFS) in QGIS?

I don't think its a problem with the servers I'm using, but more about QGIS not being connected to the internet maybe.

The pop-up error is:

Host could not be found.

Examples of servers I am using:

  1. (WFS) https://wxs.ign.fr/choisirgeoportail/geoportail/wfs?
  2. (WMS/WMTS) https://wxs.ign.fr/choisirgeoportail/geoportail/wmts? SERVICE=WMTS&VERSION=1.0.0&REQUEST=GetCapabilities
  3. (WMS/WMTS) https://portal.opentopography.org/dataCatalog?listAll=true&group=global

Version: QGIS Desktop 3.10.2

  • At least the second one works for me after bypassing the error message about certificate error. The URL to connect is https://wxs.ign.fr/choisirgeoportail/geoportail/wmts?service=WMTS&request=GetCapabilities and I tested with orthophoto layer.

  • @user30184 On my end I can't connect to any server, the hosts can't be found. Is there an option I should enable before trying to connect to a web map service?

  • Do you have a proxy server in your Network?

  • @user30184 no, I'm not using a proxy. Should I?

  • I do not know your network. If you are in a company network and external http traffic must go through a proxy server then yes, you must use proxy with QGIS as well.

1 Answer 1


I try to use the first link and it works like this:


The second link is necessary to add ? between wmts and SERVICE


Finally the last link does not have a wms service, but I found a few on the page, and I found this link: https://www.gmrt.org/services/

to visualize the service, you have to do the next steps:

  1. Right-click on WMS/WMTS on the navigation pane and click in new Connection.

  1. Enter the name of the Connection, the URL of the service, and click in Accept.

  1. Finally, you can select in the navigation pane and choose the service that you want to visualize.

  • Hi Jhon, my problem starts in your 3rd image. On my end it doesn't connect to any of the navigation services. Instead I have "Error al descargar posibilidades"
