I have installed Ubuntu 20.04 under Windows Subsystem Linux 2 and I want to perform some remote debugging with IDA Pro.

As with other VMs I have used, I can perform remote debugging when send the executable linux_server and linux_server64 to the VM and execute them. However, in WSL instance, when I run the server and use correct port and IP, there is still connection from IDA Pro to the VM, however, I kept receive this error:

In WSL instance:

IDA Linux 64-bit remote debug server(ST) v7.7.27. Hex-Rays (c) 2004-2022
Listening on 0.0.0.0:23946...
2023-03-01 09:49:40 [1] Accepting connection from 172.19.208.1...
Warning: rpc: bad packet length
2023-03-01 09:49:40 [1] [1] Could not establish the connection
2023-03-01 09:49:40 [1] Closing connection from 172.19.208.1...

In host machine: enter image description here

I am pretty sure that information in setting is true (IP, port, etc.) I have tried to config by allowing port 23946 at WSL instance but it does not work either.

Can anyone help me with this?

I do not know it is the issue or not, but when I change to Remote Debugging with Linux Debugger rather than GDB, I could do it well. I do not know sure but I also install Pwndbg along GDB, maybe it could be the issue.
