Why is my console closing after a certain time?

Is your container console or Kube-shell in Portainer closing on its own and you have published Portainer via reverse proxy?

This could be related to a time out setting in your reverse proxy and can be changed. Below are some examples of how this can be done for nginx based proxies.

Nginx Server:
add the following to the nginx.conf file.

proxy_read_timeout 3600;

_{Change the value 3600 to match your requirement.}

 

Nginx Proxy Manager:

Edit the proxy host that you need to change and add proxy_read_timeout 3600; as below.

_{Change the value 3600 to match your requirement.}

 

Nginx Ingress Controller (Kubernetes)

You need to add the following annotation to the Ingress object
nginx.ingress.kubernetes.io/proxy-read-timeout: 3600

_{Change the value 3600 to match your requirement.}
