- Start a new instance of the Proxy Server in Visual Studio and select the IP Address on your running machine you execute these projects. You can check the correct IP Address by cmd
ipconfig -allin Windows for example. The External Port must run on port5000and the Internal Port on port1587.
3.1 Next access the URL in your browser on the IP Address of your running machine you execute these projects and add the port 5000. This URL will access by the running instances. For example: http://xxx.xxx.xxx.xxx:5000
- Edit the
applicationhost.configfile indotnet-core-blockchain-advanced\BlockChainPayment\.vs\config\path and edit the following bindings by your own IP Address set by the Proxy Server in section 3:<binding protocol="http" bindingInformation="*:1587:localhost" /> <binding protocol="http" bindingInformation="*:1587:xxx.xxx.xxx.xxx" />
!Edit the URI in Index.cshtml and QrGenerate.cshtml file in the BlockChainPaymentShop with the IP Address from your workmachine but don't change the ports 5000 or 43211!Index.cshtml file:
QrGenerator.cshtml
