you can have both of them null which could be due to some other issue.

thank you for your reply, but what should I do when it occured? Close connection and unsubscribe the old subscriptionId, then resubscribe and open connection later?

Yes, after disconnect you can try reconnecting. You can also enable debug log to see xml being received and post back here if there was error but you received null.

thanks！ Now I usually create a new connection directly after the disconnect is triggered. Because I found that there are some inexplicable problems when I call open directly in ondisconnect, such as the subscription ID is empty or the connection object has been disposed
