**Hello, I have started jupyterhub as a service in dockerswarm. Without nginx reverse proxy, it works without problems. When I configure nginx reverse proxy with the following configuration:**

server {

listen 80;

server\_name [jupyter.ifora.hse.ru](http://jupyter.ifora.hse.ru);

index index.html index.htm;

access\_log /var/log/nginx/jupyter.ifora.hse.ru-access.log ;  
error\_log /var/log/nginx/jupyter.ifora.hse.ru-error.log error;

location / {  
proxy\_pass [http://172.18.207.29:8000](http://172.18.207.29:8000/);  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header Host $host;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
proxy\_set\_header Upgrade $http\_upgrade;  
proxy\_set\_header Connection $connection\_upgrade;  
}  
}

**The following messages begin to appear in the jupyterhub logs:**
