Hello John,

In general, this error is an indication of an unreliable internet connection to the SMPP server. But according to the information that you sent me by email, the evaluation period of your trial license has ended and an invalid license might also cause several issues.

You can purchase a license for Diafaan SMS Server with the purchase link on the website. Payment options include all major credit cards, Paypal and prepayment with a bank wire transfer. The license for the light edition includes one year of updates and support, the basic edition has three years of updates and support and the full edition of Diafaan SMS Server includes six years of updates and support.

Regards, Henk
