Special credential characters in extra index url

[titleistfour]

Hello we have a requirement to mirror packages from a Pip repo protected with user/pass at nautobot.jfrog.io. The username contains both a + and @ character and no matter what I try I can't get Morgan to successfully auth to that index url.

Have tried using a .netrc file with the creds there. That works just running pip command but not with Morgan. Seems to be ignored.

Also tried encoding the special charaters but it still fails.

username: manage-service+name@network.com
encoded_username: manage-service%2Bname%40network.com

url: https://manage-service+name@network.com:xxxxxxxxxxxxx@nautobot.jfrog.io/artifactori/api/pypi/pypi-virtual/simple/
encoded_url: https://manage-service%2Bname%20network.com:xxxxxxxxxxxxxx@nautobot.jfrog.io/artifactori/api/pypi/pypi-virtual/simple/

These all seem to throw the same exceptions.

[admin@server1 ~]$ morgan -i /var/www/pip_mirror -c morgan-prod.ini -I https://manage-service%2Bname%20network.com:xxxxxxxxxxxxxxxxxxxxxxx@nautobot.jfrog.io/artifactori/api/pypi/pypi-virtual/simple/ mirror

Can anyone suggest a solution for this? A better way to pass those creds in to Morgan. Thanks!
