Environment

Release : 21.x

Component: Automation Engine

Sub-Component: Agent Unix/Linux

Cause

This happens if the c-function getaddrinfo is only returning localhost for the agent instance - which means only this would be trusted 

If the job executed uses a different IP then this conflicts and is not accepted due to the TLS security.

This can be seen in the agent log ( as shown below the agent only returns the localhost ) 

=========================================================

U02000066 Host information: Host name='xxxxxxxxxx', IP address='127.0.0.1'
U02000066 Host information: Host name='xxxxxxxxxx', IP address='::ffff:127.0.0.1'
U02000066 Host information: Host name='xxxxxxxxxx', IP address='::1'

=========================================================

Resolution

You can make use of the Trusted IP's section of the agent from client 0.

Client 0 --> Administration --> <AGENT> --> Open --> Attributes --> Trusted IPs

[OR]

You can set this within the config file:
UC_EX_JOB_MD_IP_ADDR = 127.0.0.1 (or) UC_EX_JOB_MD_IP_ADDR = localhost
