Rabbit MQ : inet_error,{tls_alert,{user_canceled,"TLS server: In state connection received CLIENT ALERT: Fatal - User Canceled

[christian-dev]

Hello,
I have frequently this message in the rabbitmq logs :
{inet_error,{tls_alert,{user_canceled,"TLS server: In state connection received CLIENT ALERT: Fatal - User Canceled\n"}}}
rabbitMQ Version : 3.12.8

Could someone knows the possible root cause ?
Thanks and regards

• What version of Erlang are you using?

@christian-dev RabbitMQ 3.12 cannot run on Erlang 22. The last version to support Erlang 22 was 3.8.15, which has long been out of support.

user_cancelled means the client side of a TLS connection has terminated the handshake process.

We cannot know why that happened but we do have a methodology that helps narrow down TLS connectivity issues.
