Welcome to the Fitbit community, @Matiasmiles!

Sad to hear that you're having an issue charging your Fitbit Sense.
To hopefully get things fixed, please have a closer look here for possible troubleshooting:

Why isn't my Fitbit device's battery charging? 

I'll keep my fingers crossed.

Hi there, @Matiasmiles. Welcome to the Fitbit Community Forums. It's sad to hear that your Sense is no longer charging. Thanks for already trying to solve this issue prior to posting here. We're here to help!

As per the description of your post, it could be a sign the contacts need cleaning. Dust and debris can accumulate over time. Clean the charging contacts on the back of your device and the pins on your charging cable using the instructions in How do I clean my Fitbit device?

In addition to the steps recommended by @Talahthas, please note that sometimes a Fitbit doesn’t seem to be charging when actually the issue is that it has become unresponsive (this can happen if the battery has been allowed to discharge completely, like in your case). I'd recommend putting it on to charge on a charging wire and outlet known to be working.  Leave it on the charger for a good two hours, even if it doesn’t seem to be charging.  

When it has had two hours, try restarting your Sense. I would recommend trying this maybe twice in a row if a first try doesn’t work.
