MultiUserChatManager.create() with submit form is not joinable


I am using Smack 4.1.1 as Gradle dependency. I have successfully established connection with mine local OpenFire server.

But I have an issue while creating room from Android client.

final MultiUserChat multiUserChat = userChatManager.getMultiUserChat(roomId);
                    try {
                        LOG.debug("room created");
                    } catch (XMPPException.XMPPErrorException | SmackException e) {
                        LOG.error("create room error:{}", e);
                        multiUserChat.sendConfigurationForm(new Form(DataForm.Type.submit));                     } catch (SmackException.NoResponseException | XMPPException.XMPPErrorException | SmackException.NotConnectedException e) {
                       LOG.error("sending room configurations error:{}", e);

The most great thing is that I can see that room was created in OpenFire admin panel and get room information from another client.

try {
                        MultiUserChatManager userChatManager = MultiUserChatManager.getInstanceFor(connection);
                        RoomInfo info = userChatManager.getRoomInfo(roomId);
                        LOG.debug("room has {} occupants", info.getOccupantsCount());
                    } catch (XMPPException.XMPPErrorException e) {
                        LOG.error("join room error:{}", e);
                        final XMPPError.Condition condition = e.getXMPPError().getCondition();
                        if (condition == XMPPError.Condition.item_not_found) {
                            LOG.error("room does not exist error:{}", e);

But while trying to join room from second client I receive XMPPError: recipient-unavailable - wait.

Snippet of mine **joinRoom **method:

final MultiUserChat multiUserChat = userChatManager.getMultiUserChat(roomId);
                    try {
                        LOG.debug("joined to room:{}", roomId);
                    } catch (SmackException.NoResponseException
                            | XMPPException.XMPPErrorException
                            | SmackException.NotConnectedException e) {
                        LOG.error("error joining room {}", e);

So I am catching** error joining room org.jivesoftware.smack.XMPPException$XMPPErrorException: XMPPError: recipient-unavailable - wait. **

So the question is what can be wrong?

I also tried creating submitForm from **createAnswerForm() **method. But the result is the same.

Maybe it is a simple problem, but now I do not know how to solve this issue.

Help will be appreciated a lot.

Thanks in advance.
