@Ondřej-Šutera Thank you for your answer. Any chance you can pass the message at this source ?

Since a couple of days, this radar does not display information in Windy. It does not display also the usual "no data" but just nothing at all.

I tried to check from different computer. It's the same. I believe it's a windy problem because on accuweather shows updates.
Any chance to fix it ?
