status.json: Proxy Error updating

[alexbaltman]

Built and launched container as usual without modification. After 2-5 minutes, a red error/warning bootstrap rectangle shows up on the Zuul web page on port 80 that reads:
'status.json: Proxy Error'.

I pulled the following from a tail of the httpd logs:
==> /var/log/httpd/error_log <==

Some Extra confirmation inside the container shows:
port 8001 as open
curl http://localhost:8001 timesout
curl http://localhost:8001/status timesout
curl http://localhost:8001/status.json timesout
curl http://localhost --> Apache HTTP Server Test Page
