Mattermost Problem WebSocket

Good afternoon,

I have a pretty serious problem in my Mattermost and I wanted help to be able to solve it.

Unfortunately it leaves the server loading and can not access

I leave here an error print:

Thanks @diogorocha18! Can you help add a little more information about your environment? That’ll make it easier for community members to investigate the issue and help you out.

Some info to consider including:

  1. Which version of Mattermost are you using?
  2. A link to documentation used and the specific step at which you’re failing
  3. What variations have you made that differ from the instructions?
  4. Relevant output of error logs in mattermost.log from directory where Mattermost is installed
