Thanks for reaching out, are you able to try and log in through an alternate web browser.
Sometimes glitches can happen with web browsers and usually, a new browser or an incognito window can resolve this.
The reason I am suggesting this as a possibility is because you have mentioned it was working as normal a few days ago.
If no settings were changed in this case then please try the above-suggested resolution.
If you still continue to experience this issue please let us know.
