The default configuration exposes two HTTP ports: 8008 and 8448. Port 8008 is
configured without TLS; it is not recommended this be exposed outside your
local network. Port 8448 is configured to use TLS with a self-signed
certificate. This is fine for testing with but, to avoid your clients
complaining about the certificate, you will almost certainly want to use
another certificate for production purposes. (Note that a self-signed

termination on port 443 which in turn should be used for clients. Port 8448
is configured to use TLS with a self-signed certificate. If you would like
to do initial test with a client without having to setup a reverse proxy,
you can temporarly use another certificate. (Note that a self-signed
certificate is fine for `Federation`_). You can do so by changing
``tls_certificate_path``, ``tls_private_key_path`` and ``tls_dh_params_path``
in ``homeserver.yaml``; alternatively, you can use a reverse-proxy, but be sure

The easiest way to try out your new Synapse installation is by connecting to it

http://riot.im/app. You will need to specify a "Custom server" when you log on
or register: set this to ``https://localhost:8448`` - remember to specify the
port (``:8448``) unless you changed the configuration. (Leave the identity

following the recommended setup, or ``https://localhost:8448`` - remember to specify the
port (``:8448``) if not ``:443`` unless you changed the configuration. (Leave the identity
server as the default - see `Identity servers`_.)
If using port 8448 you will run into errors until you accept the self-signed
certificate. You can easily do this by going to ``https://localhost:8448``
directly with your browser and accept the presented certificate. You can then
go back in your web client and proceed further.
If all goes well you should at least be able to log in, create a room, and
start sending messages.
