SSL certificate error


trying to install the latest version. After updating conda I am getting though an error I havent seen before, see below. I wonder if is some security updates that our IT placed on my Mac or is it the package?
Thank you for suggestions and help.

Hi @mpodar,

Happy new year :fireworks: thanks for your patience here!

This is most likely an operating system or firewall issue on your end, and you should talk to your system administrator or IT support to work around this. Unfortunately we can’t really troubleshoot on our end since this is not related to QIIME 2 directly.

One thing I would add to this is that we now have a new version of QIIME 2 available - so after speaking with your sysadmin or IT support, I'd recommend installing that version (vs. 2022.8). Install guide can be found here for your reference.

Hope this helps! Cheers :lizard:
