When launching Plex through safari it gets stuck bouncing from plex.tv to secure app.plex.tc

I am currently using safari on my mac, and when launching plex from plex.tv it is for some reason now getting stuck bouncing back and forth between plex.tv and the secure app.plex.tv.
I am able to get in completely fine in chrome, but not safari on mac or iPhone.
Using the plex media player app for mac works fine as well as all of my other apps.
Does anyone have a solution for me? As my main browser that I use is safari, and sometimes I need to access the full site on my phone, I would like this resolved.
Thank you!
