I am using the h2o2 module to proxy calls to an external web service and the individual service works just fine. However, when I try to batch several of these calls together I end up getting a 504 error for each request. Looking for any guidance as to why proxy request might have issues with Bassmaster (https://github.com/hapijs/bassmaster).
