"Unknown Protocol" Bonsai Elasticsearch on production Heroku (rails app)

I've got a rails 5 app deployed to heroku and I'm using the Bonsai Elasticsearch plugin. I've got it configured so it is indexing and searching properly from localhost, but failing in production

I have the following gems installed per the instructions here for v6.x:

gem 'bonsai-elasticsearch-rails', '~> 6'
gem 'elasticsearch-model', github: 'elastic/elasticsearch-rails', branch: '6.x'
gem 'elasticsearch-rails', github: 'elastic/elasticsearch-rails', branch: '6.x'

When attemping to search or create an index I get the following error only in prod:

Faraday::SSLError (SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol)

Also probably worth noting I'm using the sandbox version of Bonsai and a paid heroku dyno with autoconfigured SSL.

I got in touch with Bonsai support and they offered the following information which resolved my issue:

Thanks for reaching out. The problem may be due to a breaking change Elastic introduced into the Ruby client (see the discussion here). Elastic has indicated that they're not planning to fix it.

The simple fix is to append :443 to the end of your cluster URL. In other words, something like this:

https://:@*.eu-west-1.bonsaisearch.net:443

Basically, they switched the default port from 443 to 9200 which broke many existing apps.
