Ejabberd returning 503 Service Unavailable when trying in-channel registration

Question

I've put the following snippet into my ejabberd.cfg, under the modules section:

{mod_register, [
                   {ip_access, "my.ip.add.ress"},
                   %%% some default rules included with the cfg file %%%
               ]},

Alongside this, the following access rule is in place:

{access, register, [{allow, all}]}

This was to restrict registration to a single client IP address.

While the server still works as normal for registered users, in-channel registrations cause clients to display a 503 error.

Why is this error showing up, and how can I enable in-channel registration from a single IP?

Answer 1

You may be looking for the registration_timeout option, as described in ejabberd documentation for mod_register:

registration_timeout: Timeout. This option limits the frequency of registration from a given IP or username. So, a user that tries to register a new account from the same IP address or JID during this number of seconds after his previous registration will receive an error resource-constraint with the explanation: “Users are not allowed to register accounts so quickly”. The timeout is expressed in seconds, and it must be an integer. To disable this limitation, instead of an integer put a word like: infinity. Default value: 600 seconds.
