Canon 70d error with lens

[BraCas]

I got a 70 d with a tamron 70-200 2.8. I am getting errors about cleaning the contacts, so I cleaned it. It still happens every now and then. I notice it happening during humid weather. is it truly a contact issue with the camera? or lens? is the camera going bad??

would it be a non canon lens issue??

thanks

probably a non-canon issue but how did you clean those contacts?

I wiped with my lens pen. I know I heard you are suppose to clean with and eraser to get the oils off. Any suggestions??
