OSM loads familiar tiles but not new ones

Was working fine until a couple of days ago (9th March, 2020). Now when I try a new location, I get a blank map with a pin of the target in the middle of nothing. Regularly used maps works fine; cached perhaps?
When I click the button in the bottom RH corner, it takes me to a page “Access blocked. This application is blocked for overusing OSM volunteer-run services”
How do I fix this please?

Other users reported this as well.
They also reported the error went away a few days ago.

Do you still have problems?

Thanks for asking! I switched to Google Maps and have had no problems since.
