Check#0: Always open the inputs_file.yml from the application, es and database installed location and check if the hostnames are either FQDN or valid IP addresses. Also check if the network prefix provided is not conflicting with localhost (127) or DB host, target TSSA/TSNA/SCCM hosts.

This error occurs when TSVM installer is not able to connect to the docker registry.
Check #1 - Make sure docker registry is up and running and you run the below curl command to fetch the docker repo:
curl http://tsvm-app-hostname:5000/v2/_catalog
Sample output:
{"repositories":["bmcsoftware/truesight-app-vulnerability-management-drm","bmcsoftware/truesight-app-vulnerability-management-drw","bmcsoftware/truesight-app-vulnerability-management-portal","bmcsoftware/truesight-common-discovery-connector","bmcsoftware/truesight-common-exception-management","bmcsoftware/truesight-common-orchestration-connector","bmcsoftware/truesight-common-tagging","bmcsoftware/truesight-common-tsna-connector","bmcsoftware/truesight-common-tssa-connector","bmcsoftware/truesight-common-workmanager","bmcsoftware/truesight-config-configurator","bmcsoftware/truesight-infra-ext-consul","bmcsoftware/truesight-infra-ext-redis"]}

Check#2 - Make sure that the docker registry is local to the TSVM app host.

TSVM Installation doc link: Setting up the installation environment - Documentation for TrueSight Vulnerability Management 3.0 - BMC Documentation

Check#3 - If the above 2 checks are cleared then enable debug by following the KB article:
TSVM - How to enable debug in docker and tail the logs?

Once you enable you can tail the logs. One of the issues could be related to the docker setup expecting only secure registries. This can be found in the logs if the registry link shows https URL.
To fix this issue, edit and append the /etc/docker/daemon.json to include insecure registries for both hostname and IP addresses as below:
 “insecure-registries”: [“your-docker-fqdn:5000”,”xxx.xxx.xxx.xxx:5000”]

Restart docker service and try to install again.

Check#4 - If SELinux and Firewall are enabled - then sometimes the installer wont be able to connect to database and/or docker registry and throw same errors.
Below steps can be taken to fix the db connection issue.

1. Uninstall Application only (DB and ES installs work fine)
2. Disabled SELinux on the application host
3. Run the below docker commands to clean up and setup fresh registry
   1. docker stop $(docker ps -a -q)
   2. docker rm $(docker ps -a -q)
   3. docker rmi -f $(docker images -q)
   4. Setup docker registry again:
      docker run -d -p 5000:5000 --restart=always --name registry -v /opt/tsvm/dockerrepo:/var/lib/registry registry:2
   5. Check docker images have been pulled: curl http://localhost:5000/v2/_catalog
4. Install application and validate
5. Enable SELinux
6. Start application and validate
