Constantly refreshing error

Created by: mario-mui

Due to using node-http-proxy in the website, when I refresh a certain page constantly, a error came up as follows:

Proxy error in Kibana { [Error: socket hang up] code: 'ECONNRESET' }
Proxy error in Kibana { [Error: socket hang up] code: 'ECONNRESET' }
http_outgoing.js:335
throw new Error('Can\'t set headers after they are sent.');
          ^

Using http-proxy in my code as follow:

kibana: (req, res, next) ->
      if req.url.startsWith('/kibana')
        if req.session?.passport?.user
          if req.url is '/kibana'
            return res.redirect(req.url + '/')
          else
            req.url = req.url.replace(/^\/kibana/, "")
            proxy.web(req, res, {
              target: 'http://kibana:5601/'
            })
            proxy.on('error', (err, req, res) ->
              console.log('Proxy error in Kibana', err)
              return res.redirect('/404')
            )
        else
          req.session.returnTo = '/kibana/'
          return res.redirect('/login')
      else
        next()
