Hi, I wonder if anyone can tell me what I'm doing wrong. I use a modified client1.c for getting payment objects from an aws address, curl says that the connection uses "SSL connection using TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256" if it's any use. I can retrieve any single payment object which has a content length of about 443 but when I try to get the entire record of payments of which I only need the first or latest payment to check that I'm in sync, I get "Last error was: -28928 - SSL - Bad input parameters to function". This started at a certain point in the payment object accumulation don't quite know when, the current record of all payments is 22526 and it grows with every transaction. The GET request for the all the payment objects ends in "/payments/" and for a single object /payments/ has the objects id appended to it. There must be a way to receive a truncated record of all payments. Here is my latest config.h:
