DS5-debugger cannot connect to target

I'm trying to test the DS5-debugger, I have ARM development studio professional edition with an evaluation license. For this purpose, I'm following this tutorial https://developer.arm.com/tools-and-software/embedded/legacy-tools/ds-5-development-studio/resources/tutorials/linux-application-debug-tutorial. The target board is hardkernel ODROID-XU4 running on ubuntu 18.04 Bionic Beaver, and features heterogenous Armv7 architecture. When I reach step 5 of the tutorial and click debug, the debugger tries to start for few seconds. then the following error message pops-up 

I have gdbserver version 8.3 installed on the target board, what are the possible reason for this issue, and how can I resolve it, knowing that I have full access to the device using RSE ?
