Question / Help Whenever I stream, I have a black screen

[Dax]

Hello, I recently downloaded OBS in the hopes I could stream for my subscribers for YT.
I am using a laptop (ASUS) and whenever I start to stream, I end up either my Minecraft not showing on the stream, or the stream just being completely black.
If anyone has had this problem, and been able to fix it please let me know!
Here are all of my logs:

Qualcomm Atheros AR9485 Wireless Network Adapter (802.11, 108 mbps)

Try using a wired connection instead of wireless, if possible. Also, how are your sources set up?

keyint: 60

If this stands for 'Keyframe Interval', pretty sure this should be set to '2' in OBS for Twitch

Connection to rtmp://live-lax.twitch.tv/app failed: Could not access the specified channel or stream key. This could be because the key/channel is invalid, or because the server still thinks you are logged in.

And you may want to check to see if your stream key was put in correctly
