CONNECT_FAILED_ERROR : All hosts failed DNS resolution

tbhargava18 · February 20

I am trying to establish connection from my nodejs app(angular) to solace and I am getting CONNECT_FAILED_ERROR : All hosts failed DNS resolution (error subcode 145). I am not sure what I am missing. I am able to connect to solace from my backend service using the same host and port details. From UI its giving me error

I cannot share the exact details, but url looks something like below:

url : tcps://abc.net:55443

vpnName :abc_xyz

Username and password

Can you resolve abc.net from the system, where your application is running ?

(If it is a pod in k8s: try to resolve abc.net from inside a shell in your pod).

i am trying the connection from my local machine and I am able to resolve the host from my system.

Also, I use the same details to connect from a backend service and it works. From UI it doesnt. When I open the solace dashboard using the address abc.net from my browser, I see the connection is not secure and ERR_CERT_AUTHORITY_INVALID. Could that be causing issue ?

Hey @tbhargava18 could you provide a code snippet on how you are attempting to connect to the broker?

Side note, did you get the chance of checking the solace community angular github repo? Might be helpful to get ideas on how to use angular with solace
