[Qgis-user] Problems with Plugins

[Andrea Giudiceandrea]

Hi Nicolas,
which QGIS version are you using exactly? On which operative system? 
What is the URL and the status of the plugin repositories listed in 
Plugins -> Manage and Install Plugins -> Settings? What happens if you 
click on "Reload repository"? What happens if you browse the repository 
URL using a web browser in the same system? Is QGIS, installed in your 
system, able to connect to any Internet resource (e.g. the OpenStreetMap 
XYZ Tiles server?

Regards.

Andrea
