Subdomains links broken in main menu

So. I'm new to multisite in wordpress and it's giving me a lot of pushback as I'm trying to move everything live.

I have my site set up as multisite and I finally have everything set up so the links redirect to the correct place, but as soon as I go onto one of my subdomains my main menu redirects me to my local environment instead of on the interwebs.

Please let me know if you have any idea's of what's going on and what I should try doing to fix it.

Thanks so much!
