Connection Pool Full

[sfmajors373]

Hi,
I am following the tutorial to get started with PySyft for Android: https://towardsdatascience.com/pysyft-android-b28da47a767e
I have the android app running, the server is running, the socket is started but when I run bob.connect() I get this error in the notebook:

W0804 11:37:27.632236 140307790296832 connectionpool.py:275] Connection pool is full, discarding connection: localhost

and this in the WSGI terminal:

Dear all, may I ask how to clean or close the connection pool or can we adjust the size of the connection pool? What is the best timing close the connection and reopen?
