Hi,

I am using MPOS with retail proxy which uses its own built-in hardware station using hardware station URL as "ipc://localhost". Out of box it works well, but as soon as I build the hardware station solution and replaces the dll's in retail proxy it stops working.

Check your dlls version and make sure it matches the one specified in the Retail Server's web.config

Hi,

I would recommend to set breakpoint in hardware station controller in MPOS Client and debug. You will receive extended error description and will be able to fix issues.

In my case I needed to fix the following after deployment of Hardware Station from SDK (I didn't only change DLLs but made 'Publish'):

1) Change Retail Server URL in Hardware station web.config to point to correct server;
2) Sign projects in Visual Studio with a key;
3) Change assembly version + public key for DLLs in web.config to be equal to built DLLs;
4) Change user for Hardware Station application pool to have access to required folders.

Regards,
Oksana

Hi, this is not the issue i am facing, because i do not use Hardware station as a website. My mpos uses Client Broker present at default location "C:\Program Files (x86)\Microsoft Dynamics AX\60\Retail Modern POS\ClientBroker". In this case client broker creates a local httpserver to host Hardware station and do all the post request to it.
