Got connection lost with self host n8n on k8s contour envoy proxy

Hey @thanhpd56, welcome to the community!

The UI would show the connection lost message when it’s unable to reach the server. Are your containers perhaps crashing or is your proxy service interrupting the connections for any reasons?

Hi, thanks for your help.
I deployed n8n on k8s, and sure that container still working as normal.
Maybe the issue comes from contour envoy proxy, I have tried to reconfig with connection iddle timeout = infinity, but it still not working. :frowning: Documentation
Do you have any experience with it.
Thanks in advanced.
