Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_EXPIRED

Hi people,
Im new to unity and game dev. I have been working on a project for a number of weeks now. All of a sudden out of nowhere and for no reason I keep getting the following error pop up in the console log. Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_EXPIRED
Can anyone shed some light on this for me please. Im using Unity 2019.3.0f6
Thanks

me too, I think this is a Unity server error or something, lot of user sudenly attacked by this error

probably because unity3d.com is down :smile:

Ahhh right, I see thanks.
