Humph, no I have not. Are you running through a proxy of any kind?

Phorcys•3y ago

I think I have seen this before, as kyle said, are you using a reverse-proxy?

Oh yeah, sollution was adding a couple headers in the nginx conf file

Phorcys•3y ago

yup, could you send them here just for the record?

map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
}

server {
  # your server block here

  location / {
    proxy_pass_request_headers on;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Accept-Encoding gzip;
  }
}

map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
}

server {
  # your server block here

  location / {
    proxy_pass_request_headers on;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Accept-Encoding gzip;
  }
}

alright, marking this as resolved actually can't do it because i'm on mobile but in a bit btw, @kyle can you pin this?

kyle•3y ago

Sure!

kyle•3y ago

roshaan•3y ago

is this what you guys use in nginx?

kyle•3y ago

We don't currently proxy via nginx in our dogfood deployment (it lives at dev.coder.com).
