Hopefully is a bug and not intended.

The app works fine if using clean wifi connection, but ignores vpn (regardless if over wifi or cellular). Error code: 0x204

RD Client iphone over VPN on wifi or cellular was working fine a few versions ago (before 10.4.5 and 2021s). The cause might be shared with ios upgrades BUT i have tested other apps with different protocols http, samba, ftp, ping etc, all work over VPN.

Its my partial conclusion that RD Client iphone is ignoring all network interfaces other than wifi.

Remote desktop constrained to a wifi range is barely remote. Dear developers, please bring back RD Client iphone to its glory.

Hello Arigato, I am having a similar issue with error 0x204. 

 

I have tested iPad connected to wifi via my Verizon hotspot, iPhone as a hotspot, and two other backup cellular connections.  If I connect to Verizon, or either of the two backups (all 3 of these have IP addresses that start with 192.168.1.....) and then connect to my company's VPN the RDClient app gives me the Error code: 0x204.  However, when I connect my iPad to my iPhone hotspot (IP 172.20.1......) and the VPN, RD Client connects.  I mention the IPs because the desktops I'm attempting to connect to are also on a subnet that coincidently start with 192.168.1.....  My Network Admin thought that may be playing a part of the issue. 

 

I tested these same 4 wifi connections in conjunction with VPN on my windows laptop using the native RDP and all combinations worked.

Confirmed on latest release as of writing v10.4.6 (5273). VPN interface is ignored when disconnected from wifi. Same host is accessible from web browser or other RDP apps.
