When i try to login a text that says "Sorry! Make sure you are online and try again!" appears, some help?

When try to login to the Minecraft Launcher it says "Sorry! Make sure you are online and try again!" The password and email are right, i'm 100% sure. I have this problem for 2 weeks, in the first week i had an other account and with that i could join servers. Now i don't have it anymore and i can't log in. I really hope you would help me.

 

I don't know why people send their launcher_Log, if it helps for the error here's mine
