    proxy_read_timeout 36000s;
}

}

I installed linux packages loolwsd, but when i trying use docker, i have same errors

I solved this problem. Check in your nginx config string

add_header Content-Security-Policy “default-src ‘self’; script-src ‘self’ ‘unsafe-eval’; style-src ‘self’ ‘unsafe-inline’; img-src ‘self’ blob data:”;

if you had - comment this.
Also you need chek in loolwsd.xml your nextcloud hostname in storage.wopi and webdav. And your nextcloud server must resolve your owncloud hostname
