Can’t get into yahoo mail from home

For the past week, I haven’t been able to get into my yahoo mail. I can get into www.my.yahoo.com but can’t get into it my mail once I get there, I’m not sure what it is, I have even restored the computer back to an earlier point before it started acting up, but it keeps saying ” The page cannot be displayed”, everytime I try to get into my mail . I have done every option it isssued but still can’t seem to make it work
