Hi,
I have deployed in Kubernetes and exposed with path base ingress under /mm, but i am facing this web socket issue, please help me to fix this issue,
I have attached my ingress resource file for reference.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: mattermost-ingress
namespace: mattermost
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /mm/$2
nginx.ingress.kubernetes.io/proxy-read-timeout: “3600”
nginx.ingress.kubernetes.io/use-regex: “true”
nginx.ingress.kubernetes.io/ssl-redirect: “true”
nginx.ingress.kubernetes.io/enable-cors: “true”
nginx.ingress.kubernetes.io/cors-allow-origin: “*”
nginx.ingress.kubernetes.io/configuration-snippet: |
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection “upgrade”;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
spec:
ingressClassName: nginx
rules:

  • host: devops.assam.statedatacenter.in
    http:
    paths:
    • path: /mm(/|$)(.*)
      pathType: ImplementationSpecific
      backend:
      service:
      name: mattermost-service
      port:
      number: 8065

See if Integrations configuration settings - Mattermost documentation helps.

Hi, Issue has been resolved by adding the following lines in the ingress file

nginx.ingress.kubernetes.io/configuration-snippet: |
   proxy_http_version 1.1;
   proxy_set_header Upgrade "websocket";
   proxy_set_header Connection "Upgrade";
