If you host your domain with another hosting provider and you want us to do Jabber hosting you have to set some DNS SRV and DNS CNAME entries into your DNS zone file. Many providers allow you to do that, if not, the provider has to do this for you.
(As an alternative you can deligate a subdomain, for example jabber.domain.tld, to our DNS servers and we take care of everything else. Your hosting provider must allow you to do this as well.)
Please set the following entries:
_xmpp-client._tcp.domain.tld. IN SRV 0 0 5222 jabber.hot-chilli.net.
_xmpp-server._tcp.domain.tld. IN SRV 0 0 5269 jabber.hot-chilli.net.
_xmpps-client._tcp.domain.tld. IN SRV 0 0 443 server.jabber.hot-chilli.net.
_xmppconnect.domain.tld. IN TXT "_xmpp-client-xbosh=https://jabber.hot-chilli.net:443/http-bind"
_xmppconnect.domain.tld. IN TXT "_xmpp-client-websocket=wss://jabber.hot-chilli.net:443/xmpp-websocket"
This is how it looks in BIND9 zone files. A web interface of your provider might look different, but the data you have to enter is mostly the same.
Additionally you need a proper SSL certificate for your domain. If you do not provide one, we will use the *.hot-chilli.net certificate for your domain, too.
If you have any problems, don’t hesitate and contact us.
