HI All, I’m using 0.49 version and I would like to setup it behind AWS ELB and RDS MySQL, but I’m getting following error: > time=“2015-12-08T23:16:59Z” level=fatal msg=“Unable to start event router” error=“websocket: bad handshake” I’ve configured also Proxy Protocol to enable WSS traffic but nothing change… any idea? Proxy Procol ref: > **[Configure proxy protocol support for your Classic Load Balancer - Elastic...](https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-proxy-protocol.html)** > > Enable or disable support for proxy protocol, a human-readable header, for your Classic Load Balancer. Thanks Jo ---

Hi @miticojo, The UI also uses websockets to dynamically update. Can you check whether the UI is successfully making websocket connections? To do so: 1. Open up rancher in your browser 2. Open up the developer tools for your browser and go to the network tab, 3. Refresh the browser. You should see a request to /v1/subscribe. Was it made successfully and is the response code to that request 101 “Switch Protocols”? Also, can you give a little more information about your setup: 1. Are you running rancher in [HA mode](http://docs.rancher.com/rancher/installing-rancher/installing-server/multi-nodes/) or in [single server mode](http://docs.rancher.com/rancher/installing-rancher/installing-server/)? If in HA mode, is the websocket proxy container up and running successfully? 2. Do you have any other proxies between rancher-server and your ELB? ---

@miticojo It should say `101 Switching Protocols`, not `200`. Besides Proxy Protocol, you need the listener and target in ELB to be TCP/TLS, not HTTP/HTTPS because they don’t support WebSockets in HTTP mode. ---

Ah sorry guys… I’ve changed ELB to TCP/TLS and now it works as expected! 😃 Thanks for your precious help! My next step is try to test HA conf… I will keep you updated! 😉 Jo ---

@miticojo check out [https://github.com/SungardAS/particles-rancher](https://github.com/SungardAS/particles-rancher). Even if you don’t use condensation the CloudFormation scripts can be used by clicking the ‘Launch Stack’ buttons. It will give you HA multi-node rancher with Zookeeper, RDS MySQL, Elasticache Redis autoscaling groups and load balancers. -Kevin ---

Thanks but I’d like to setup all with 3 AWS instances + RDS… and I’ve almost finished but HA documentation need to be changed and explained using some beautiful schema.
