On the ACM server.log, the following error is observed:

When using Linux DNS servers, port 53 should be enabled between the IDPA Proxy and the DNS server. TCP port 53 being blocked either on the DNS server or in network firewall can cause this issue. By default, this port is disabled on Linux based DNS servers.
From the output above, notice that proxy was not able to obtain the correct Hostname and hence, localhost.localdom was set as the hostname which caused the issue.
In a Proxy Deployment workflow, after the IP address gets assigned to the Avamar Proxy, it tries to reach the DNS servers to lookup the hostname for the same. After a successful reverse lookup from the DNS, it then assigns the same hostname to the Proxy. If, for some reason, proxy is unable to reach the DNS servers or if it does not get the response or incorrect response, the proxy hostname gets marked as localhost.local.dom.
This results in the proxy deployment failing and the proxy gets deleted as part of cleanup steps in PDM.
Verify if port 53 is blocked between the IDPA Components and the DNS servers
Run the following commands to test if the server is blocked:
