Hello there !
I am using a VPN called "Freedom-IP" using OpenVPN technology.
I was often using a french server, but i couldn't use it anymore (same problem) so i switched to another one that worked for a few days and now I can't connect to this one either.
Sometimes I don't have any problem to connect to any server, but sometimes I can't do anything, I don't really understand and I am a huge noob in network.
I have already cheched, the DHCP service is working well.
Here are the logs :
