One website URL redirects to another website (Multisite configuration)

Hello.

I have a multisite network in WordPress. One of the sites that I have (https://www.pucnational.org) redirects to my main website (https://www.pucschools.org) when I remove the www. In other words, when I go to https://pucnational.org, I get taken to https://www.pucschools.org. The strange thing is that in Chrome, I don’t get redirected to the wrong site. It works just fine. But in using Firefox, or even my phone, I do get redirected to the wrong site. I have a feeling there is a setting (or settings) that I need to update in WordPress, I just don’t know which one(s). Please help!

Thank you.
