By exchanging eduroam Server certificates, clients on which eduroam access is set up report a certificate warning. Since the old certificate has expired, the new certificate must be confirmed here, otherwise eduroam access is not possible.  In principle, however, it is no longer recommended to configure eduroam manually, but to set it up again using the CAT tool. Instructions can be found on the GWDG help pages. This ensures that all clients use eduroam are set up according to current security requirements.
