So it turns out that it was my own fault! Or rather, the person who set it up before me. They didn't put any values for DNS into the idrac settings, which was probably on purpose to restrict it from the internet. So I put in DNS settings for 1.1.1.1 and voila, success! I used the HTTPS method and put in the address downloads.dell.com Thanks [NAME] -Charles R for your help in getting me to think about checking network settings and your helpful replies that taught me some things.
