Front end maven plugin 500 error code

We have been using the plugin for over 8 months. Since the last few weeks, we have intermittently run into the following issue with the plugin. I looked at similar issue https://github.com/eirslett/frontend-maven-plugin/issues/551 but I doubt if the root cause is the same.

[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.9.1:install-node-and-yarn (install node and yarn) on project xxxx: Could not download Yarn: Got error code 500 from the server. -> [Help 1] [ERROR]

Yes, that’s what I’ve done using Nexus to mirror the Node and NPM download services.
