无法从 docker 实例连接到本地 MQTT 服务器（在 Windows 10 上运行）

Question

RabbitMQ server is running locally on Windows 10 and docker is running on it also. I'm running a device simulator on docker and it has to talk to local RabbitMQ server through MQTT. It had been working but one day it stopped. Here is device logging -

mqtt-client.cpp:322 | Failed to connect to broker at 'xxx@xxx.xxxxxx.com/:1883': code=15, message='Lookup error.'

Keep in mind that from docker(latest version) calls have been made to local web server which has exact domain name -

https-commissioning-channel.cpp:81 | [HttpsCommissioningChannel] using token to contact bootstrap service at 'https://xxx.xxxxxx.com/apibst/alo/v1/bootstrap/device-info'

So you can see domain name has been resolved. For firewall configuration port is open on 1883 (consider it had been working). RabbitMQ is running.

What might be the issue and what should I do to make the call go through?

Answer 1

As per the comments xxx@xxx.xxxxxx.com/:1883 should not contain a slash ( xxx@xxx.xxxxxx.com:1883 ) - see the URI Scheme .
