title: 504 Gateway Time-out from google cloud platform, but only sometimes
body: <p>I'm hosting a CouchBase single node cluster in GCP and a flask backend OpenShift cluster which supports angular frontend. The problem is, when a post is called in my flask by my angular, it is taking too much time to get connected the VM (couchbase) and hence flask has to return a "504 Gateway Time-out". But this happens only sometimes. Sometimes it just works very well with proper speed. Not able to troubleshoot. The total data size is less than 100M, and everything is 100% memory resident in Couchbase. So I guess this is not a problem with Couchbase. Just the connection latency to GCP.</p>
