Can't get messages from users not in contact list.

[homocogitum]

I can't get new messages from people that I don't have in my contact list. WhatsApp can do it.

It would be helpful if you included the parts of log (`/var/log/spectrum2/<jid>/backend/backend.log`) when someone not in your contact list sends you a message.

Log: http://pastebin.com/LdCtbbEW
It seems that transwhat is receiving messages but somehow they are lost.
In the given log 3 users that are not in my contact list tried to write me messages, but I don't receive them.(numbers 79035712277, 79030225580, 79188748667)
But after 10-15 minutes of waiting I received messages from 2 of 3 users that wrote me. The message from third user remained unreceived.
So I think that some problem definitely exists.

Try stopping transwhat and then deleting `/var/lib/spectrum2/<jid>/<number>/axolotl.db` and check if the problem still persists. This could be related to #33.

[homocogitum]

Yes, deleting axolotl.db helped.
Still there are some error messages before sending/receiving some messages in log, such as

ERROR yowsup.layers.axolotl.layer: No session for: 79035714477, 1
ERROR yowsup.layers.axolotl.layer: No valid sessionsBad Mac!
ERROR yowsup.layers.axolotl.layer: No such signedprekeyrecord! 45324 

But everything works fine now.
So, can you say what may be the problem? Is there something wrong with database? Do you know what can be done to make it work without deleting database?

[homocogitum]

The problem occured again! And deleting axolotl.db did not help this time.
Before deleting there was following error message: http://pastebin.com/6cGU4rgv
And after I deleted the database file, the error message dissapeared, and instead of it another message appeared in the logs - many messages appearing 6 times in a second until user disconnected:
ERROR yowsup.layers.axolotl.layer: No such signedprekeyrecord! 28098
Can you fix this problem please? Or maybe you can tell me how I can fix this problem myself.

[moyamo]

Did yowsup regenerate the axolotl.db? Have you tried to restart spectrum? You should stop spectrum before you delete the axolotl.db

[homocogitum]

Yes, i restarted spectrum2.
And axolotl.db is regenerated.
Try yourself to get messages from people not in your contact list. You will see this error.

[moyamo]

1. First check that you are running on the latest develop branch of transwhat.
2. Check you are running the latest version of yowsup.
3. Stop spectrum
4. Delete all the axolotl.db files
5. Start spectrum again
6. See if problem persists

[homocogitum]

Do I have to use yowsup from develop branch as well?

[homocogitum]

Tried all above, the problem still persists.
I can see in backend logs that someone is typing a message, but it is not delivered.
I can see such lines of log:

2016-03-21 21:29:43,426 INFO Session: Presence received: None None 380979439330@s.whatsapp.net None

2016-03-21 21:31:49,309 ERROR Session: Buddy not found: 380979439330

But these messages are among many such messages:
ERROR yowsup.layers.axolotl.layer: No such signedprekeyrecord! 28098
That are appearing several times in a second.

[homocogitum]

It seems that it's happening with only some of users that are trying to send a message to transport. Most messages are delivered, but some of them are not.

[Myppomeu]

For me it works the same: in xmpp-client I did not see if someone send me a message.

Is there any way to receive messages from user which not in contact list?
