To provide more info on this. We have received a list of red listed countries that needed to be blocked via our firewall. When we did that none of our TouchApps applications worked (Trip Tracker or Scan It to name a few) as they returned error 500. 

We went with our gut feeling and unblocked India as a country and things went back to normal but ideally we want to put it back on blocked countries list and use IP address that touchapps use to whitelist it and allow it to work while the country inbound and outbound traffic is blocked. 

Thanks,

Hi Kasia,

You mentioned both the Uplink and the TAS, but you’d only have one the the two, never both. Can you confirm what you use please?

To clarify, if you’re currently using the Touch Apps Cloud (which by the way is going to be decommissioned by 1st March 2023), then you’d be using the Uplink. In this case, the Uplink (hosted on your infrastructure) needs to be able to reach cloud.ifsworld.com which is hosted in Azure’s North Europe region, and the Touch Apps Cloud in turn needs to be able to reach your Uplink as well. If this is your setup, then sounds like your Uplink is hosted in India. The good news though is that your apps only need to reach cloud.ifsworld.com, so you don’t need to worry about access.

If you have the on premise Touch Apps Server, you don’t need the Uplink, but in this case all your apps need to be able to reach your TAS. If this is your setup, either you TAS appears to be hosted in India, or some of your apps are running on mobile devices are running in India.

Hope this helps.

Cheers,

Thank you so much for your answer. Yes I’m away of Touch Apps Cloud decommissioned. 
We managed to resolve this issue by by allowing traffic from and to clound.ifsworld.com whilst having countries blocked. 

Thanks,
