MQOPEN gives error 2085, which I didn't have before - c

Question

I have everything was working OK, until today I on MQOPEN got error
2085 MQRC_UNKNOWN_OBJECT_NAME

for(i = 0; i < MAX_NUM_OPEN_QUEUES; i++)

sQueues[i].IsSyncpointControled = 0;
break;
}
printf("In the loop\n");
}
printf("QDESC = %d\n",qd);
return DTE_MQR_OK;
}
Function call is:
qd = -1;
dteretopen = dteMqOpen(QName, &qd);
printf ("Return code from dteMqOpen = %d\n",dteretopen);
if (dteretopen ==0)
{
printf("MQOPEN could not open MQ, check errpr log\n");
exit(99);
}
Error 2085. But several days before there was no such error
Connection is OK, but MQOPEN failed

Answer 1

dteretopen = dteMqOpen(QName, &qd);
Clearly 'QName' has an invalid value.
You have been posting question after question about the same program. Obviously, you have zero training in MQ programming. You need to get some MQ training ASAP. There is lots and lots of information on the web and videos too.
Why aren't you doing some basic debugging and outputting 'QName?
You need to take some initiative in debugging your program before posting questions here. We are not here to do your work.
