Re: PYro4 v4.17 and HMAC_KEY error: hmac key config not symmetric

Hi Irmen,
the code is failing when starting the server.
The nameserver and server are hosted on the same machine and I
suspected nameserver needed the HMAC_KEY but I could not find a way to
set it: could you help me with setting that key?
Once done, I'll give you a feedback on this.

Thanks in advance,
Aurelio
