Hello PB Community,
a customer of ours complained that our application is apparently contacting servers on the internet and not starting up correctly, if he blocks internet access (which he wanted to do in his industrial environment).
We have our applications running in complete offline environments, so I think the fact that the application is not starting up correctly, when the customer blocks internet access, has somenthing to do with HOW his security software blocks the internet access of our application - and probably blocks the further excution of our software altogether.
The thing that we are interested in is: So far, we were not aware that our PB applications (currently compiled with PB 2021) are contacting any third-party web-services.
I have attached a log/screenshot from that customer claiming our application is trying to connect these HTTPS services during startup. It seems that at least 2 of these servers belong to Microsoft. This is not something we have implemented, we are not using any web-serivces from our application!
Is anyone aware of this?
Can this be proven wrong or correct?
If this is the case, does anyone have an explaination which third-party services are contacted by the PowerBuilder runtime / included frameworks and for what reason?
Thank you in advance.
