Good morning, I went though a lot of reviews looking for a solution but I didn’t find anything related to this issue so I decided to contact you guys and ask for help.
I’ve been using this app (Microsoft Remote Desktop) on my Ipad for a long time, but now that I got a new Ipad (software version 14.8.1 ) I am getting this error: “Unable to connect, Error code 0x204”
This issue happens only when I am connected via VPN using T-Mobile network. When using VPN on a WiFi network it works perfectly, it also works fine when used via WiFi within the same network where my computer is connected here in my office.
(I also tried on my Iphone and same situation, same error message under the same conditions, it doesn’t work on T-Mobile network via VPN )
The bad (or good) thing is that everything works perfectly on my “old Ipad” no issues at all, it works everywhere on any of those conditions mentioned above, the software version of my old Ipad is 12.5.5
Any ideas on how to make it work on my new Ipad Air 4th Generation?
Thanks in advance.
Thank you Ale_rod1500,
Unfortunately using hostnames did not work for my VPN.
not exactly, I have to go back to where the problem started: on my new Ipad the RDC app didn't work when connected VPN using T-Mobile network to access my PC , after some research I noticed that the fix was to add my PC to the RDC App using the PC host name (instead of IP), the pc name found in Windows - Control Panel - System - <System Name> and with this modification the connection started to work when VPN using T-Mobile from anywhere.

Hi Ale_rod1500 ,
When you mention using a DNS, what do you mean in particular? i.e. setting up a DNS on a home network or registering with a dynamic DNS server.
Thanks

Hi Ale_rod1500 ,
The app engineering team does not have any guidance to provide related to your Remote Desktop issue at the time as it seems mostly related to accessing session hosts via VPN using T-Mobile network which is not an issue they have seen/delt with before.
Have you filed a support request for this issue yet? Hands-on debugging with our customer support team sounds like the next best step.
Furthermore, have you looked at Remote Desktop clients FAQ | Microsoft Docs. Specifically there is a section on "VPN doesn't work" which includes:
VPN issues can have several causes. The first step is to verify that the VPN works on the same network as your PC or Mac computer. If you can't test with a PC or Mac, you can try to access a company intranet web page with your device's browser.
Other things to check:
- The 3G network blocks or corrupts VPN. There are several 3G providers in the world who seem to block or corrupt 3G traffic. Verify VPN connectivity works correctly for over a minute.
- L2TP or PPTP VPNs. If you are using L2TP or PPTP in your VPN, please set Send All Traffic to ON in the VPN configuration.
- VPN is misconfigured. A misconfigured VPN server can be the reason why the VPN connections never worked or stopped working after some time. Ensure testing with the iOS device's web browser or a PC or Mac on the same network if this happens.
How can I test if VPN is working properly?
Verify that VPN is enabled on your device. You can test your VPN connection by going to a webpage on your internal network or using a web service which is only available via the VPN.
How do I configure L2TP or PPTP VPN connections?
If you are using L2TP or PPTP in your VPN, make sure to set Send all traffic to ON in the VPN configuration.

Hi Ale_rod1500,
There shouldn't be anything specific to the RD client running on your old iPad's software vs your new iPad's software that would affect error code 0x204. Is this error reproducible? Or has it just happened a couple times?
