Cisco ASA : HA- Active/Standby. ssh connection problem with 'Master'

[aymanbounagua]

I have a Cisco ASA5516 configuration: HA- Active/Standby.

The ssh is enabled on the outside and all interfaces, but the active ASA keeps rejecting the ssh connections for about 20 minutes, and then everything works as expected. The odd part is that this stop-and-start issue happens randomly, without a clear pattern.

Configure SSH Access in Cisco ASA

Step 1: Configure Enable password. (Optional)

ASA(config)# enable password system@123

Step 2: Create a username with password.

ASA(config)# username gowherm password cisco@123

Step 3: Configure this local username to authenticate with SSH.

ASA(config)# aaa authentication ssh console LOCAL

Step 4: Create RSA key pair.

ASA(config)# crypto key generate rsa modulus 1024
INFO: The name for the keys will be: 
Keypair generation process begin. Please wait...

Step 5: Now specify only particular hosts or network to connect to the device using SSH.

ASA(config)# ssh 192.168.1.0 255.255.255.0 trust
ASA(config)# ssh 172.16.1.0 255.255.255.0 trust

I hope you have followed the above steps to configure the ssh in ASA.
Please  make sure and check the logs 

You can now access the device using SSH from 192.168.1.0 and 172.16.1.0 network.

Thanks for the reply we are sure that the ssh is configured correctly and the firewalls are in production.
