Hi,

im getting 502 Error after upgrading to Version 6.0

i Addet the Cable
location /cable {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header CLIENT_IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 86400;
proxy_pass http://zammad-railsserver;
}

But it doesn’t change a thing.

My Ngnix config.

so, if redis was not started, postinstall script aslo not executed.
no redis → error 502
no postinstall script running → weird things with zammad.
