Push Notification Error 1704 when trying to "subscribeToChannel"

Question

Hi, 

I have been testing my IOS app using pp42HQ Push Notification service.

For testing purpose, I created 1 channel and my app then needs to subscribe to that channel. I have done a few times subscribing and unsubscribing the same channel.

Now when I tryt to "subscribeToChannel" Again I receive the error  1704: "User by name xxx  already subscribed for channel yyy".  (Of course I subscribe the channel after I've unsubscribed the channel) However, I cannot understand what is going on?  And what should I be doing to clear this.

I am  confused and my app is also confused.  Please help.

And if you need more information, please let me know.

Thanks!

Daryl

Hello Daryl,

 

You don't need to worry about it, the exception message which you have shared is occur  due to the username which you want to subscirbe is already subscribed to that channel. Kindly unsusbcribe user from that channel and susbribe it again to overcome on this issue. If you still face an issue than let us know we are happy to serve you.

Hi Himanshu,

I guess I have ever deleting the channel without unsubscribing the user from it.  Would it mess up the system?  I cannot 100% describe the situation, but I am quite sure that I receive this error with the same username to a NEW channel.

Please advise!

Thanks!

Hi Himanshu,

App42Response *app42Response = [pushObj subscribeToChannel:channelString userName:deviceUser];

and this:

App42Response *app42Response = [pushObj unsubscribeFromChannel:subscribedChannel userName:deviceUser];

Thanks!
