failed: amqp:connection:framing-error SSL Failure

[vishavjeet somwanshi]

Hi Team,

We did encounter with one of the issue today where skupper is exposed from SITE A ( namespace a ) to SITE B (namespace b). I could see the skupper link status in namespace b states that "Links created from this site: Link  <link_name> is connected. However services are not getting exposed. 

Upon checking further in skupper-router logs in site B, getting below error in log file.

Assuming you're using skupper version 1.x, there are a couple of things you can look at:

- First make sure all your pods are running on both namespaces (a and b) without

  crashes or restarts.

- Verify if you don't have extra links defined on your namespace. The following command

  should tell you links you have on a given namespace:

      kubectl get secret -l 'skupper.io/type=connection-token'

- Ensure that the Hostname or IP Address of the target site is correct, usually if you are using

  a LoadBalancer ingress (default on kubernetes - not on OpenShift), you can look at the

  External IP of the skupper-router service then compare it with what is defined at the

  inter-router-host annotation of the secret(s) returned in the previous item.

I hope it helps.
