[stable/graylog] Got html response loading js files with 2 replicas of GL server

Having deployed the Graylog helm chart with one server pod the UI stuff loading as expected. But with 2 replicas the script responses for some reason have an Html instead of a JS file. I have noticed that requests can be performed to a random server and the responses come from the other node that is different from the initial request.

For example the first request:

Request:
 Request URL: http://graylog.foo.bar/
 Request Method: GET
 Status Code: 200 OK
 Remote Address: xx.xx.xx.xx.80
Response:
 X-Graylog-Node-ID: 1f3d2f34-315c-4ba3-be0b-1c2c1052a23a
