PGP Send Key

Hello,

I need send keypair and public key for the keyserver.

1- Create the keyrings;

2- Create user keys;

3- In this moment, I executed the following command:

pgp --keyserver-send xxxxx --keyserver ldap://keys.xxxx.xxx

Results of command:
pgp:keyserver send (2710:days left in current license, 11)
xxxxx:keyserver send (2509:keyserver error)
ldap://keys.xxxxx.xxx:keyserver send (3090:operation failed, Server is unwilling to perform)

How can resolve this problem?

Thanks,
