Leaving this open for now, but I changed the user_agent in praw.ini from test (duh) to mfaimagebot. I suspect lots of other people are using test so hopefully a more unique user agent will resolve this.

See this thread: https://www.reddit.com/r/redditdev/comments/9mkjiq/error_httpsconnectionpoolchange_max_retries/

Might need to configure a cert for this as well, but that's more complicated so I'll just watch for more of these errors for now.
