          <p>You don't have an IPFS node running at <code>{opt.addr}:{opt.port}</code> or it is not reachable.
          The IPFS Boards prototype requires a full IPFS node. Please start one by following the
          <a href="https://github.com/ipfs/go-ipfs"><code>go-ipfs</code> documentation.</a></p>
          <h5>Do you have a running node but the app won't work?</h5>
          <p>It's probably one of these issues:</p>
          <ul>
            <li>Your node is not located at <code>{opt.addr}:{opt.port}</code>. Go to the <Link to="/settings">Settings Page</Link> to configure the connection.</li>
            <li>You edited your settings and saved them but didn't reload the page</li>
            <li>Your IPFS node doesn't allow requests from the domain you're running the app from (CORS issue). See <a href="https://github.com/fazo96/ipfs-board/blob/master/ipfs_daemon_set_cors.sh">here</a> for the fix.</li>
            <li>You're downloading the app via `https`: at the moment, connecting to IPFS only works if you donwload the app via plain HTTP. If you're using `ipfs.io` please consider accessing the app via a local gateway like `localhost:8080`</li>
            <li>Some other networking or browser security issue is preventing the App from talking to your node.</li>
          </ul>
          <p>Still can't fix it? <a href="https://github.com/fazo96/ipfs-board/issues">File a issue on GitHub</a>, we'll be happy to help!</p>
