Due to compliance issues, users of a PS3 Pro certificate issued before 11/11/2020 need to migrate to a new certificate. This migration must be done before 23/02, because on 24/02 the current certificates will be permanently blocked. Issuing a new certificate is free of charge.
If you have a certificate that needs to be re-issued, you have already received a message from GlobalSign. We advise you to carefully follow the steps mentioned in this mail. In case you missed this mail, you can also find all information here.
