Contributed pack can't be downloaded if behind the proxy

[PFerro]

I have this tracback when I try to get the “contributed pack”.
Do imagine why?

Traceback (most recent call last):
File "C:/Users/pedro.ferro/.qgis2/python/plugins\quick_map_services\settings_dialog.py", line 86, in get_contrib
error_message = self.tr('Error on getting contrib pack: %s %s') % (sys.exc_type, sys.exc_value)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe7 in position 50: ordinal not in range(128)

Hi, are you behind proxy by any chance?

[PFerro]

Yes.

Is that the problem?
