Daiki Ueno created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1421

When the client requests session ticket and has received a NewSessionTicket in the first handshake, the second handshake fails as it waits for NewSessionTicket while the server doesn't indicate sending it. Simple reproducer would be to configure Apache httpd with TLS 1.2 as the maximum protocol version and expose a protected resource as:
SSLProtocol all -SSLv3 -TLSv1.3

<Location /client>
        SSLRequire true
        SSLVerifyClient require
        # SSLVerifyDepth  10
        # SSLOptions +StdEnvVars

and access the resource with gnutls-cli.
