java.net.unknownhostexception: host.docker.internal
is an error that occurs when a Java program is trying to connect to a hostname that cannot be resolved to an IP address. This can happen for several reasons, such as a typo in the hostname, a network issue that is preventing the hostname from being resolved, or a problem with the DNS configuration on the system.
To troubleshoot this error, you can try the following:
ping
or
nslookup
command.
host.docker.internal
DNS name to access the host from within the container. This name resolves to the IP address of the host machine from within the container. However, this may not work if you are running the container in a different network or if the host machine is not reachable from the container.
If none of these steps help, you may need to check the logs or seek further assistance to determine the root cause of the issue.
