Zimbra limit token

Good afternoon. I have installed privacyidea with zimbra and as soon as I add 50 tokens it gives me external LDAP auth failed error, LDAP error: - unable to ldap authenticate: Failed to authenticate. Wrong HTTP response (400);

In _data / privacyidea.log appears

[2020-07-03 20: 13: 14,759] [278] [140009758959424] [INFO] [privacyidea.api.lib.postpolicy: 487] There is no machine with IP = IPAddress (‘127.0.0.1’)

I have changed the value action: ** {u’tokenissuer ‘: u’Zimbra’, u’tokenlabel ‘: u’ domain.com ‘, u’max_token_per_realm’: u’1000 '} ** and nothing.

This might be helpful
