unable to open the chase bank website

Normally I open all my financial institutions and bank websites on my home computer no issues.  Today, I was unable to open the Chase Bank website.  Other financial websites opened fine.  Tried opening the Chase Bank mobile app on my iPhone and also unable, perhaps because my iPhone was operating on my home wifi.  Changing my iPhone off wifi to just 4G, the Chase Bank app was able to be opened.  Is my Xfinity IP address for some reason being blocked by the Chase Bank websites?  How can I fix this. Always worked fine up to today.  Unable to open via Microsoft Edge or Chrome on my home computer.
