I am trying to use msticpy.vis.timeline. However, I am having the following error:

from msticpy.vis.timeline import display_timeline

ConnectError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)

Hi @sidraaleem-eaton I am having trouble replicating this issue.
Can you please provide details of what environment you are running this code in?

The only thing I can think can be causing this is fetching the Bokeh JS libraries. There should be no network/https access happening otherwise during import.
I think if you are behind a corporate firewall/proxy this could be the cause - the firewall is proxying the TLS traffic and returning its (self-signed) cert to Python. Since Python doesn't have this cert in its root store the https connection is failing.
Here's a discussion I found and links to ways to fix it by importing the cert into your Python cert store.

There is definitely network access during import (working in a restricted environment myself at the moment). Not sure if this is the same root cause of the above, as my error is not certificate-related, rather a total connection error, but also happening at import time. It is caused by this line in context/ip_utils.py that is triggered on import.

_ASNS = httpx.get("https://bgp.potaroo.net/cidr/autnums.html")

We should fix that import-time network fetch.
I've submitted a PR for that.
