Newly created Couchbase cluster stuck in pending, rebalance fails, error log says {{badmatch}}

My company is moving to Azure and we are trying to configure Couchbase in the cloud. Right now, we have a cluster with two nodes. The nodes constantly show an offline state. Attempting to rebalance always fails. When we recreate the bucket, It will show offline for a few minutes but then go to a failed state afterwards. We’ve uninstalled Couchbase multiple times, but the issue persists. We are unsure how to move forward from here.

We are using Windows Server and Couchbase 4.1.
