Troubleshooting
1

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)
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):

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?

2

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

3

I updated the desktop client to the latest version (1.3.0), still seeing the issue.

4

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 :slight_smile:

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”;
}
