Sling doesn't work on Safari

I've noticed for the past few months that Sling doesn't work right away on safari. Specifically https://watch.sling.com/ does NOT load. It says "unable to load server" or whatever. It does this for about 10 minutes and then it starts working (typically once I begin searching "why isn't sling working on safari" and it magically starts working... The other way I get it to work is by restarting my whole computer, which I have to do about 3-4 times a day now and I hate doing. BTW, this is a new MacBook Air that I got in December 2022 (its August 2023), I should have no problems with it. I also have very good home WIFI, so that's not the issue either. I believe this is 100% an issue with Apple/Safari, and NOT Slings fault. Is anyone else having this issue?
