1051254 - Firewall or antivirus blocking SAP Business One components

Please find the original document at https://launchpad.support.sap.com/#/notes/ 1051254

 Symptom

One of the following may not work properly:

SAP Business One license service

•SBO Mailer

•DI API

•DI service

•integration framework for small and midsize enterprises (B1i)

Cause

A user´s operating system, firewall, or antivirus program may be blocking the ODBC/COM/UDP or TCP IP communication protocols, causing SAP Business One components that use these protocols to fail.

License Service:

This communication requires an unblocked networking infrastructure because in addition to the well-known and configurable ports, it uses some dynamically assigned TCP IP ports which cannot be changed. These dynamic ports change each time the license service is started. In the advanced network infrastructure, it is difficult to allow some exceptions for randomly assigned TCP IP ports for the license service.

Because the SAP Business One component requires a direct communication with the license service (B1 Client, DI API, DI service, B1i, etc.), no network limitation should be set.

SBO Mailer:

The main policy here is to allow the outgoing communication for the TCP IP port of the SMTP server, which has been defined for the SBO mailer configuration.

Integration Framework:

If B1i does not require any interaction with the B1 license service, then the network can be easily configured because B1i uses static TCP IP ports for communication (for example, 8080, 8443, 8005, 2099, and so on). On the other hand, they are changeable if they can be configured according to the network and user requirements.

Solution

Ensure that your operating system, firewall, or antivirus program is not blocking any of these protocols
