Hello community.
I have a problem, we have CCO installed with B1, this client is already in production. Since 2 months ago. Today when trying to transmit the receipts to CCO Manager, the following message appears.

I already checked the connection with manager and it's successful so you shouldn't have problems sending the receipt.

The error log in the cco cdm shows me the following message:
Caused by: java.net.SocketException: Connection reset

And the modification log shows a different error and is recorded at a different time, so I understand that the error has nothing to do with the problem. Therefore, I ask for your support to know what may be causing this problem and how it can be solved.
CCO: 2.0 FP13 PL01
Integration Framework : 4.0.44



Thanks!!
