SM-G891A – Phone Connect Failed (GS7A)

My Octoplus does not recognize the Galaxy S7 Active. Debugging is enabled, it is in MTP mode, the Samsung driver has been installed, and I am using a Micro USB cable. The port it is communicating on is correct and the same as the Octoplus.

My computer has no problem seeing the phone and allowing me to explore its folders and files.

How do I fix this?
