I just noticed that one of my servers is missing it's SDKey. I found this info with TIDS 3092072 and 3455150.

Per TID 3092072 I tried to issue new Keys with SDIDIAG with the RD command, but SDIDIAG failed with an error:
"error -249 retriving keys from server. xxxx.chi.usa.twusa" Where XXXX is the server without keys. I ran the command from a server with keys.
