Your user is BF82a4mCHgYsQVeATQQ2Xq9Mh71SX4CqM2? (found it in another post).

I took the last rejected solution from the log files and validated it again. Here is the result:

{'Command': 'hexblocktocoinbase', 'biblehash': '000003dec5371466195741c313bec6d7c3bf4caa4f22620e4c25935ac0a3c322', 'blockversion': '1.1.2.3', 'txid': '6787e37242ae8bf17d32c6de65a4a825c45cf5679e81141fb3685538062d2d37', 'cpid_legality_narr': 'CPID_HAS_NO_MAGNITUDE', 'subsidy': 512, 'recipient': 'BA3cgTBNea2jrChntZQz4fJbNFzyGtuttx', 'blockmessage': '1.1.2.3f75aecf265ef66a949ddfc750f9e45f1;a4fcf89390f6f275f829cb81d2e417bebdbd37fbb86f950fd5367ce796c042aa;BF82a4mCHgYsQVeATQQ2Xq9Mh71SX4CqM2;H50EBoglQCEmp4JaxHQAg+skgCgugJWDJ65Ssla52asnIY6yKu3bn7T9x8qpvkyc4uflxtunQMb9tWG02PNjSHc=ada16105-5246-41bb-93e6-b1f05c1da42c', 'cpid_legal': False, 'cpid_sig_valid': True}

Important are the parts with "cpid_*":

'cpid_legal': False
'cpid_sig_valid': True
'cpid_legality_narr': 'CPID_HAS_NO_MAGNITUDE'

This is the output of the biblepay client on the pool.

If I use the given CPID, I see the problem:
  "42452 [04-24-2018 04:53:04] (24549 BBP) [TXID=16f0996ea97dc16059d5884e5184cacb7a831ce65fc21d804973df40eb70d125] ": "0.41",
  "41692 [04-20-2018 08:19:23] (23634 BBP) [TXID=1ebdeb465bd61b59f9b70432914b61479c67fdec3e7d145b5ae1141ccc14dc18] ": "3.86",

You had a long time without any podc updates from a biblepay client. For that reason, you have no magnitude.

Important: The same rules the Pool is using are used by all other clients, too. So if you would, for example, solo mine, your found blocks would be rejected by all other biblepay clients for the same reason. It is not a pool rule, it is a network rule
