Without dockerized attribute getting Connect to dev tools Error: HTTPConnectionPool

[pmohite@ancestry.com]

HI team ,
our wpt server are running on K8-docker where are using official wpt server docker image

our wpt agent machine we have built from scratch by following installation step
(non docker structure)
OS : amazon linux 2 (centos)
agent : 200604.150630


when we are running wptagent with dockerized command its wrking
sudo python ~/wptagent/wptagent.py --server <server> --location <location> --key <key> --xvfb -vvvvv

but when we are running without dockerized attribute its not working

sudo python ~/wptagent/wptagent.py --server <server> --location <location> --key <key> --xvfb --dockerized -vvvvv

getting errors as

22:43:22.957 - Connect to dev tools Error: HTTPConnectionPool(host='localhost', port=9222): Max retries exceeded with url: /json (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7fc76c697ad0>: Failed to establish a new connection: [Errno 111] Connection refused',))


we have tried
1. increasing CONNECT_TIME_LIMIT to 60-300 seconds (refernce : https://www.webpagetest.org/forums/archi...022-2.html)
but no success


one more thing even its is getting passed with dockerized attribute results data is bit skewed pls refer image wptissue.png.

we are able to resolve this issue by passing --ec2 instead of --dockerized attribute
