Hello,
I’ve installed Mattermost on the fresh Ubuntu 20.04 VM. But I have this problem:
{"level":"error","ts":1626871612.3405845,"caller":"mlog/log.go:251","msg":"Failed to upgrade websocket connection.","path":"/api/v4/websocket","request_id":"esazb6p8u7go3j37pu4rxgy9yc","ip_addr":"127.0.0.1","user_id":"5p4gp6bi7inwbdm6gnagz4kdmr","method":"GET","err_where":"connect","http_code":500,"err_details":"websocket: the client is not using the websocket protocol: 'upgrade' token not found in 'Connection' header"}
Here is my config details:
