SMPP stopped working

Hello

I'm using traccar + opensmppbox + kannel.
For 3 months the solution worked... now I get this error when trying to send SMS:

Traccar web interface:

Submit SM failed - IllegalStateException (SmppClient:247 < NotificatorSms:55 < NotificationResource:63 < ...)

Traccar seems to connect with user&pass to opensmppbox but can't see any error related to the problem...
Please advise.
Thanks.

There seem to be a problem also with the traccar server... 99% of events fail to trigger... no matter if the notification is web, email or SMS... can't find any problems in logs...
