RabbitMQ remote error connection to Lightsail (Ubuntu instance)

Question

I have this urls RMQ options which works fine on local MacOs machine

{ urls: ['amqp://127.0.0.1'] }

Then I installed RMQ on a remote machine at AWS Lightsail (Ubuntu) and opened the necessary ports

Custom  TCP  5672
Custom  TCP  15672

I successfully logged in remote UI with previously created new user credentials

http://my.com:15672  

But any of this configs are not work for remote RMQ server connection for data passing.

{ urls: ['amqp://my.com'] }
{ urls: ['amqp://my.com:5672'] }
{ urls: ['amqp://login:[email protected]'] }
{ urls: ['amqp://login:[email protected]:5672'] }
{ urls: ['amqp://2.50.11.117'] }
{ urls: ['amqp://2.50.11.117:5672'] }
{ urls: ['amqp://login:[email protected]'] }
{ urls: ['amqp://login:[email protected]:5672'] }

I have this error

 [Nest] 90314  - 01/26/2024, 5:59:47 PM   ERROR [ClientProxy] Disconnected from RMQ. Trying to reconnect.
