Web Filter with WARN action problem

Hello Community,

we have UTM 9 SG430 with Web Filter at standard mode.
After upgrade firmware from 9.508-10 to 9.601-5 is a broken URL with WARN action,
as seen in the images. There are also logs from communication with WARN action
before upgrade and after firmware upgrade.
Could anyone advise me what to do to make the WARN URLs work again? Thank you.
Regards

Peter
