Can't connect to ssl with self signed cert

[hadmut]

Hi,

I'm having a test case with rabbitmq 4.05 (latest docker.io/library/rabbitmq:4.0-management-alpine docker image cb4b6dc2960e ) running with a self signed TLS certificate. Running on Ubuntu 24.04 with amq-tools Version: 0.11.0-1build2

openssl correctly shows the certificate running on port 5671.

ruby with the bunny library can successfully connect both

plaintext with url amqp://name:password@ipaddress/test to port 5672 and
encrypted with amqps://name:password@ipaddress/test to port 5671

the amqp-tools do work with plaintext as well

amqp-consume -u "amqp://name:password@ipaddress/test" -q queuename cat

but not with tls. Neither

amqp-consume -u "amqps://name:password@ipaddress/test" -q queuename cat

nor

amqp-consume -u "amqps://name:password@ipaddress/test" -q queuename --cacert=certfilepath cat

do work. It just says

opening socket to ipaddress:5671

and terminates without further comment, and exist status 1

No error message, no verbose mode, no flag to not verify the cert, just no way to start debugging.

Would it be possible to improve debugging and issue some information about why it fails?

And shouldn't it be able to connect to a server with self-signed certificates?

best regards
