Website does not load after login prompt

I have a website for work that I typically login to 3-5 times a day on my phone. One day last week it stopped working. I am able to go to the page to login but after putting the credentials it goes to a white page and sits loading completely. I have cleared cache cookies and history. I’ve used incognito in chrome, safari and Mozilla and edge. This still does not work. I used my wife’s iPhone to login and it works immediately. I’ve used my spare android phone and it also works. Does anyone know why specifically my phone 13 pro does not work?
