In my app I have in the page properties an URL defined (e.g. /contract/{Id}). When navigating to the page, it shows the url correctly. (e.g. www.website.com/p/contract/123456789). However when I refresh the page on this URL I recieve a IIS generated ‘404 Page not found’, which means i will not be able to use as a deeplink either :-(. Note! This only happens in our cloud environment, on my local machine it works like a charm. We have an On-Premise installation on IIS with Mendix 8.6.4.5823 and there is a request handler added for /p/. It’s likely to be some IIS configuration which is the cause. Any ideas?
