Encountering 504 when attempting to download packages from SoapUI Repo

Hello,

Currently, our team is encountering issues in building our packages when using the SoapUI maven plugin. Every attempt to download the package from the repo is met with the error:

 Failed to transfer file: http://www.soapui.org/repository/maven2/com/oracle/servicebus/client/maven-metadata.xml. Return code is: 504 , ReasonPhrase:Gateway Time-out

We have also confirmed this is the case when attempting from a public host to confirm it's not a firewall/network issue. Is the repository currently experiencing an outage? Are there any workarounds or alternate repos we can use?

Full output of an example below:
