#### Summary I am getting websockets error when upgraded to mattermost v3.3.0 #### Steps to reproduce Installed mattermost 3.1.0 via docker. Upgraded to 3.3.0 using these steps: Fetch the repo again ([https://github.com/mattermost/mattermost-docker.git](https://github.com/mattermost/mattermost-docker.git)) and set HEAD to `3.3.0` tag. $ docker-compose build $ docker-compose up #### Expected behavior Should boot up the containers and run properly #### Observed behavior See this error in the logs (host URL changed): ```auto db_1 | LOG: database system is ready to accept connections db_1 | LOG: autovacuum launcher started db_1 | LOG: incomplete startup packet app_1 | Configure database connection...SKIP app_1 | Wait until database db:5432 is ready... web_1 | Starting Nginx web_1 | ln: failed to create symbolic link '/etc/nginx/sites-enabled/mattermost': File exists web_1 | 2016/08/20 06:34:53 [error] 11#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 106.51.15.26, server: , request: "GET /api/v3/users/websocket HTTP/1.1", upstream: "http://172.17.0.3:80/api/v3/users/websocket", host: "example.com" web_1 | 106.51.15.26 - - [20/Aug/2016:06:34:53 -0400] "GET /api/v3/users/websocket HTTP/1.1" 502 583 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Mattermost/1.3.0 Chrome/51.0.2704.84 Electron/1.2.2 Safari/537.36" app_1 | Starting platform web_1 | 2016/08/20 06:34:53 [error] 11#0: *3 connect() failed (111: Connection refused) while connecting to upstream, client: 106.206.147.201, server: , request: "GET /api/v3/users/websocket HTTP/1.1", upstream: "http://172.17.0.3:80/api/v3/users/websocket", host: "example.com" web_1 | 106.206.147.201 - - [20/Aug/2016:06:34:53 -0400] "GET /api/v3/users/websocket HTTP/1.1" 502 583 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/537.36 (KHTML, like Gecko) Mattermost/1.2.1 Chrome/49.0.2623.75 Electron/0.37.8 Safari/537.36" web_1 | 2016/08/20 06:34:53 [error] 11#0: *5 connect() failed (111: Connection refused) while connecting to upstream, client: 106.51.15.230, server: , request: "GET /api/v3/users/websocket HTTP/1.1", upstream: "http://172.17.0.3:80/api/v3/users/websocket", host: "example.com" web_1 | 106.51.15.230 - - [20/Aug/2016:06:34:53 -0400] "GET /api/v3/users/websocket HTTP/1.1" 502 583 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_0) AppleWebKit/537.36 (KHTML, like Gecko) Mattermost/1.3.0 Chrome/51.0.2704.84 Electron/1.2.2 Safari/537.36" web_1 | 2016/08/20 06:34:53 [error] 11#0: *7 connect() failed (111: Connection refused) while connecting to upstream, client: 103.252.24.109, server: , request: "GET /api/v3/users/websocket HTTP/1.1", upstream: "http://172.17.0.3:80/api/v3/users/websocket", host: "example.com" web_1 | 103.252.24.109 - - [20/Aug/2016:06:34:53 -0400] "GET /api/v3/users/websocket HTTP/1.1" 502 583 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Mattermost/1.3.0 Chrome/51.0.2704.84 Electron/1.2.2 Safari/537.36" ``` On the client mac app `v1.3.0`, getting some 404 error. Cannot see any online users (even though they are online) Tried restarting the client-app and containers. PS: There is no error if I view the website via browser. Am I missing something in the upgrade? ---

I’m seeing the same issue on desktop clients. Must be an API change. ---

I’m experiencing the same issue. EDIT: nvm. I’m experiencing this issue regardless of the mattermost version. I’ll be opening up my own issue sometime 🙂 ---

You need change location. location /api/v3/users/websocket { proxy\_pass http://mattermost\_proxy; proxy\_http\_version 1.1; proxy\_set\_header Upgrade $http\_upgrade; proxy\_set\_header Connection “upgrade”; }
