Google PubSub Not pulling new data

Having an issue with the google pub/sub input plugin, I got it setup and it pulled in a bunch of records but hasn't/won't pull any new items down. Wondering if anyone has experience with this plugin or this behaviour. It's not logging anything in the logs about being unable to connect or anything like that. My logstash node does have to traverse a proxy to get out to it.

    google_pubsub {
        project_id => "xxxxxxxxx"
        topic => "xxxxxxxx"
        subscription => "xxxxxxxx"
        json_key_file => "/etc/logstash/files/xxxxxxxxx.json"
        codec => json
        max_messages => 100
    }

Never mind, found my issue
