POS cannot connect to Dynamics 365 (Real-time service)

POS cannot connect to Dynamics 365 (Real-time service)

Description

Accidentally my POS became unable to connect to D365 – real-time service functionality started to throw communication exception (notifications, create/update customer order, product availabilities).

I restarted DevBox machine in LCS, but this did not help.

Solution

1. Try to browse failing URL in browser link – my browser was not able to display any information, it was reloading page again and again
2. Clear cache in browser (Internet Explorer in my case) – and POS was able to communicate with D365 again.
