Hi,
There was a known issue with Firebase Console today [1], November 1st, 2021, which might have impacted Firebase Storage. The issue has since been resolved. However, if you have a mechanism to handle errors in your app [2], I suggest verifying what the error message being returned says in order to get a better idea of what could be the root cause.
If the error returned suggests that the issue might be specific to your project, then contacting Firebase support [3] directly for further assistance would be the next best step I recommend.
