Not sure why I am getting turn socket failed (turnSocketDidFail called). Anybody can help me in figure out this? Please point me what am I doing wrong here. I know there are lots of question like this and I have already checked all of these and from that I have taken little help already. One of client is Spark and other is simulator.

Settings:
Server: testXyz
Senderjid: user1@testXyz
Receiverjid: user2@testXyz

XMPPJID *jid = [XMPPJID jidWithString:Receiverjid];
[TURNSocket setProxyCandidates:[NSArray arrayWithObjects:Receiverjid, nil]];
TURNSocket *turnSocket = [[TURNSocket alloc] initWithStream:self.chatManager.xmppStream toJID:jid];
[turnSocket startWithDelegate:self delegateQueue:dispatch_get_main_queue()];

Update

If I am changing:

[TURNSocket setProxyCandidates:[NSArray arrayWithObjects:Receiverjid, nil]];

to:

[TURNSocket setProxyCandidates:[NSArray arrayWithObjects:Server, nil]];

It gives me:

<error code="503" type="cancel"><service-unavailable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error>.

As suggested in one of question on stack to resolve this error I have replaced Receiverjid: ‘user2@testXyz’ by ‘user2@testXyz/spark’ but am still getting same error.

    Don’t know what to set in setProxyCandidates, but I am setting my Server name.

    <error code="503" type="cancel"><service-unavailable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error>

    Solution: Pass full jabber id:username@domain/resource.
    In my case I have changed ‘user2@testXyz/spark; to ‘user2@testXyz/Spark 2.6.3’

    I don’t know how to find these resource parameters. I have checked XMPPJID class’s resource parameter but it is nil. I found these parameters by seeing some console logs. If anybody know how to find this from any xmpp class then please let me know.
