I'm completely new to RabbitMQ and now I'm looking for a configuration error. The client doesn't receive any messages from RabbitMQ and I debugged it as far as possible.
Frontend messages:
Message 1:
CONNECT
login:frontend_listener
passcode:xxx
accept-version:1.0,1.1,1.2
heart-beat:20000,0
Message 2:
ERROR
message:Bad CONNECT
content-type:text/plain
version:1.0,1.1,1.2
content-length:30
Virtual host '/' access denied
There are two vHosts: / and someVhost and there are different users like frontend_listener. Now I found a way to access the log file.
RabbitMQ log file:

It reads like the permissions are wrong. Can someone help me out interpreting that correctly?
I try to read it: User frontend_listener wants to access the vHost /, but it hasn't sufficient permissions (don't know what $ here mean other than a part of regular expression). The thing is, that I don't know if that is the correct vHost. How do I find out the URL of each vHost?
I'm asking this because I believe that the mapping to the vHost is wrong or something is missing.
Edit:
After adding host: 'someVhost' to my stomp-config.ts I was able to subscribe to the queues. Now I get the following error in the log:
2020-02-12 16:32:25.913 [error] <0.5159.1> Channel error on connection <0.5149.1> (127.0.0.1:58136 -> 127.0.0.1:15674, vhost: 'someVhost', user: 'frontend_listener'), channel 1:

On the frontend I don't get a message or error.
You need to also pass host information in the STOMP CONNECT frame..
this is what the specifications says and clients MUST set this header
host : The name of a virtual host that the client wishes to connect to. It is recommended clients set this to the host name that the socket was established against, or to any name of their choosing. If this header does not match a known virtual host, servers supporting virtual hosting MAY select a default virtual host or reject the connection.
So this is how your CONNET frame should look
CONNECT
login:frontend_listener
passcode:xxx
accept-version:1.0,1.1,1.2
host: someVhost
