SAP Customer Checkout - Customer Sync failure

[former_member12197]

Hi,

One of our CCO Terminal started acting weird lately that we couldn't synchronize customer data from B1. We don't knwo when, how it is happening. All the other terminals are just fine.

Whereas article sync goes smoothly without any error.

when start customer sync, it displays the tomcat error below, it is not even reaching the server.

Please take look below. Is there anything I can do to fix this? I wonder if any accidental change was made to any file which is not supposed to be touched or sth.

Thank you

Dear baigalmaa ,

The error message is "connection refused" which clearly indicates you do not have a working connection to B1i. If other terminals are working correctly, then make sure that the name "sapb1server" resolves to the correct IP address and make sure no firewall is blocking the connection.

Hope this helps.

Best regards,

Joerg.

Hi Joerg,

Connection to B1i alright. The Article Sync, Receipts Post on the exact same machine works just fine. But not the customer sync.
I even tried the customer request on postman on the exact same machine, and it gives the response. But POS itself displays the error.
It just happened out of no where.

Thanks.

Maybe some Antivirus software interfering?

I have this exact scenario where i cannot sync customer from my external data, but i can successfully sync article data into my cco .

Please help me to clear this error
