Unable to connect - try again later

In this specific case the problem is due to the fact that the Web Bridge is not able to resolve the DNS SRV record for _xmpp-client._tcp.domain.com.

To resolve this the record can be created on the appropriate DNS servers or alternatively the MMP command example below for customer Resource Records (RR) can be used to enabled the DNS resolver(s) to return values which are not resolvable from the configured DNS servers. Note the _xmpp-client SRV record is still required externally for use by the Acano/Cisco App (Windows/OSX/iPhone etc.). Without the record, testing results in the Application crashing or failing to join spaces in the case of an iPhone client.

dns app add rr “_xmpp-client._tcp.domain.com. 86400 IN SRV 10 10 5222 edge1.domain.com.”
