Infura IPFS SSL certificate verification fails

Hello!

I just updated to ipfshttpclient from py-ipfs-api and I'm now having trouble connecting to Infura's IPFS endpoint.

Infura IPFS multiaddr: base_uri = "/dns/ipfs.infura.io/tcp/5001/https"

Connecting to Infura IPFS

self.client = ipfshttpclient.connect(self.base_uri)

Stack trace:

I'm not sure what I could be doing wrong. There doesn't seem to be any problem with infura's ssl certificates. It appears that the multiaddr is being correctly parsed, since the request is being made to https://ipfs.infura.io:5001/api/v0/version. Any thoughts or ideas on what could be the issue would be great, cheers!
