RabbitMQ bad_ssl_dist_optfile - docker

Question

so I'm working on getting RabbitMQ up in a clustered setting, and I "think" I have the configuration to have the cluster nodes talk to each other over SSL, but when running the nodes, I get this error:
rmq-node-1 | {{shutdown,
rmq-node-1 | {failed_to_start_child,ssl_dist_sup,
rmq-node-1 | {'EXIT',
rmq-node-1 | {{bad_ssl_dist_optfile,
rmq-node-1 | 16:36:58.591 [error] {failed_to_start_child,ssl_dist_sup,
rmq-node-1 | 16:36:58.592 [error] {'EXIT',
rmq-node-1 | 16:36:58.592 [error] {{bad_ssl_dist_optfile,
rmq-node-1 | ["/etc/rabbitmq/inter_node_tls.config"]},
rmq-node-1 | [{ssl_dist_sup,consult,1,
rmq-node-1 | [{file,"ssl_dist_sup.erl"},{line,105}]},
rmq-node-1 | 16:36:58.593 [error] ["/etc/rabbitmq/inter_node_tls.config"]},
rmq-node-1 | {ssl_dist_sup,start_link,0,
rmq-node-1 | [{file,"ssl_dist_sup.erl"},{line,45}]},
The gist of the error is the line that says bad_ssl_dist_optfile and I'm thinking the configuration is part of the problem. I've been following this guide: Securing Cluster Communications - Option 2 - config files
I also generated the pem files with the recommended "easy" solution. (also did the same with easy-rsa and got the same issues.) automated certificate generation
I've setup my folder structure like so:
I've created a compose file to include all the files, variables, and configuration:
I've created a rabbitmq.conf, rabbitmq-env.conf, and inter_node_tls.config to complete the setup:
RabbitMQ Config
RabbitMQ Env
Inter Node SSL
Am I missing a piece of the configuration? or is there some issue with formatting on the inter node configuration?
EDIT: I did catch the file name issue with the TLS config file, but got the same issue.
