PLEASE HELP XFi is blocking my safe work website

So this is pretty insane. I’m working from home, I’ve been accessing my work website perfectly fine for the last few months, and all of a sudden last night I can longer access it in my browser. It’s saying it cannot establish a secure connection. I logged into XFi because I figured my ISP (Xfinity) was the one blocking this and sure enough I have multiple threats detected for this exact domain. So essentially XFi is incorrectly flagging my safe work website as malware. The problem is when I go to my threat detection in XFi and click allow access, it only allows access for 1 hour and then after that, it continues to go back to blocking it. I need to find a way to either permanently allow access to this domain or turn off protected browsing. I can’t find that option anywhere in the XFi app. I could really use some help here because I’m unable to work at this point.
