First of all, thanks for the great work on developing Fireworks! I’ve been using the package for a while, and it’s been a great tool for running my workflows.
I seem to be running into an issue when trying to connect to a mongoDB atlas server with the new version (v1.8.9). Here’s the trace when trying to connect to the mongoDB database using lpad get_fws:

During handling of the above exception, another exception occurred:

raise ValueError(err_message)
ValueError: FireWorks was not able to connect to MongoDB. Is the server running? The database file specified was /Users/mbercx/Dropbox/python/sandbox/fireworks/my_launchpad.yaml.
The issue can be reproduced by setting up a conda environment and installing fireworks via pip:
conda create -n test
conda activate test
conda install pip
pip install fireworks dnspython
and trying to get the fireworks from the following launchpad file using lpad get_fws:
host: mongodb+srv://tutorial-urpwq.gcp.mongodb.net
name: test
port: 27017
username: tester
password: fireworks123
ssl: true
authsource: admin
If I set up a new conda environment and pip install fireworks v1.8.8, everything runs smoothly, so it seems to be related to the final update. Any ideas on how to fix this?
Kind regards,
Marnik
