400 Bad Request

Hi 👋

when I try and open pages off a certain email and click link to say an article to read, I get 400 Bad request. It was once and a while at first, and now it’s all the time. I have reatartes iPhone 13 pro max and it would allow 1 to open, now that doesn’t fix it. Today, it allowed one article to load, but the next it wouldn’t. How do I fix the 400 Bad request on my side. I know it’s client because my husband has ability to open same said article link.

thanks
