SMS Server exception occurred


I’m trying to set up SMS server without success.
I am in Openfire version 4.7.5, build ee4395e.
No worries about the configuration part, I have correctly entered my SMPP server and the port.

But when I do tests the page hangs for several minutes and in the end I have this message in the logs:

2023.12.14 15:37:31 ERROR [Jetty-QTP-AdminConsole-6301]: org.jivesoftware.util.SmsService - An exception occurred while sending a SMS message (to '***********' )

I can’t get any more logs

you can help me ?


Oh, it has been a while since I looked at SMPP. That error should be logged together with a stack trace. Can you share that?
