-105 - Unable to initialize OBServerDLL.dll

I’m developing an application in VS2015 to transfer data from our ERP system to SAP B One. I’m using two similar developing environments. On these environments the same SAP B One Development Environment and DI API (32 bit) is installed.

The first environment is in the same network as the SAP B One server. While debugging in VS2015 on this environment we can connect to the SAP B One DB and transfer data to SAP B One.

The second environment is at a remote location where I’m working. Both networks are interconnected via VPN’s. When I try to connect to the SAP B One DB, I always get following error after +/- 3 minutes: “-105 - Unable to initialize OBServerDLL.dll”.
When I start the SAP B One client in this environment, I can connect to the SAP B one DB. It takes a long time but it works.

I checked several topics that explain the origin of this error (,, and they all suggest that the used license server or license server port is wrong. I checked it over and over again and the used license server and port is correct and the same as used in first environment.

Does anybody know why I get this error and how to solve it?

    Have you already tried uninstalling, and then re-installing the DiAPI from the server installation package (not the installer from the b1_shr) ?
