PAPI_Send failed

Hi community, 

 

I have got a cluster of 2 Access Points IAP-305. Since some days ago, clients who connect to the Slave AP are getting trouble, they do not get IP Address.

 

DHCP Server is on the Master AP, we think there must be any sync problem between Master AP and Slave AP,  so Slave AP clients are not able to receive IP address from DHCP Server.

 

Cluster System log ("show log system") shows some errors: 

 

Master AP

AP <IP_MASTER_AP>: Client <MAC> authenticate fa
il because integrity check failure in encrypted message

 

PAPI_Send failed, send_papi_message_w
ith_args, 1079: No such file or directory, dstport 5664

 

Slave AP

AP <IP_SLAVE_AP>: Client <MAC> authenticate fa
il because integrity check failure in encrypted message

 

PAPI_Send failed, send_papi_message_w
ith_args, 1079: No such file or directory, dstport 5664

 

 

Does anyone know what these error messages mean?
