I guess the keys on the server were updated but not written into the keytab. Can you try if kinit -k -t /var/lib/ipa/gssproxy/http.keytab HTTP/ myhost.mydomain(a)MYDOMAIN.COM returns the same error ((preauth (encrypted_timestamp) verify failure: Preauthentication failed)? In this case you should update the keytab with ipa-getkeytab and restart httpd.
