+# The key "<your key>" under "env" in next.config.js is not allowed.
+
+#### Why This Error Occurred
+
+Next.js configures internal variables for replacement itself. These start with `__` or `NODE_`, for this reason they are not allowed as values for `env` in `next.config.js`
+
+#### Possible Ways to Fix It
+
+Rename the specified key so that it does not start with `__` or `NODE_`.

+# onDemandEntries WebSocket unavailable
+
+#### Why This Error Occurred
+
+By default Next.js uses a random port to create a WebSocket to receive pings from the client letting it know to keep pages active. For some reason when the client tried to connect to this WebSocket the connection fails. 
+
+#### Possible Ways to Fix It
+
+If you don't mind the fetch requests in your network console then you don't have to do anything as the fallback to fetch works fine. If you do, then depending on your set up you might need configure settings using the below config options from `next.config.js`:
+
+```js
+module.exports = {
+  onDemandEntries: {
+    // optionally configure a port for the onDemandEntries WebSocket, not needed by default
+    websocketPort: 3001,
+    // optionally configure a proxy path for the onDemandEntries WebSocket, not need by default
+    websocketProxyPath: '/hmr',
+    // optionally configure a proxy port for the onDemandEntries WebSocket, not need by default
+    websocketProxyPort: 7002,
+  },
+}
+```
+
+If you are using a custom server with SSL configured, you might want to take a look at [the example](https://github.com/zeit/next.js/tree/canary/examples/custom-server-proxy-websocket) showing how to proxy the WebSocket connection through your custom server

+# Custom server with Proxying onDemandEntries WebSocket
+
+## How to use
+
+### Using `create-next-app`
+
+Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
+
+```bash
+npx create-next-app --example custom-server-proxy-websocket custom-server-proxy-websocket
+# or
+yarn create next-app --example custom-server-proxy-websocket custom-server-proxy-websocket
+```
+
+### Download manually
+
+Download the example:
+
+```bash
+curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/custom-server-proxy-websocket
+cd custom-server-proxy-websocket
+```
+
+Install it and run:
+
+```bash
+npm install
+npm run ssl
+npm run dev
+# or
+yarn
+yarn ssl
+yarn dev
+```
+
+## The idea behind the example
+
+The example shows how you can use SSL with a custom server and still use onDemandEntries WebSocket from Next.js using [node-http-proxy](https://github.com/nodejitsu/node-http-proxy#readme) and [ExpressJS](https://github.com/expressjs/express).
