503 Service Unavailable “http://maven.tealiumiq.com/java/releases/com/tealium/java/1.3.2/java-1.3.2.jar”

Below, I attempted to download the Tealium java-1.3.2.jar both through the Jenkins CI pipeline and via the terminal. Both methods resulted in the following error, and I have been unable to identify the root cause or a solution. What could be the issue here

Attempting to download using Jenkins CI pipeline:
