Go to API access in settings and turn on all the options in there. Try it and it might work.
By the way, are you using the VPN in whonix system for any specific purpose?
The whonix system runs the entire system network on the TOR network. Using a VPN in Tor destroys anonymity and can cause errors if not configured properly, you failed to connect, presumably due to misconfiguration.

I can’t directly connect TOR, I need set VPN

where is API setting ?

First, about the API
1

Second, I feel that the first one is not very useful

  1. You use whonix, and using a VPN in a TOR network requires additional configuration. But I’m not a Linux user (whonix is Linux) and can’t tell you the details of how to do it (warning: this breaks tor anonymity)
  2. How can you use whonix ?
    (1) Install whonix directly in a computer
    You need to configure the VPN network in a router before you can use whonix (a soft router is also possible), and there are many related to this on the web tutorials.
    (2) Use virtual machine, for example, install virtual machine software in Windows, and install whonix in the virtual machine, this way is the most convenient, just connect VPN in Windows, and share the network to the virtual machine.

I used translation software, so forgive me if the tone and ordering is wrong

you mean API … all API can’t connect

…god damn

I set Mullvad 's XTLS Bridge

and …

You might want to use a Tor bridge instead. You can get them via email: bridges@torproject.org or Telegram: (@GetBridgesBot)

Tor is running

Tor is running?
Have you solved it yet ?

from Whonix Official Link

Tor is running , but VPN not running

I run in Vitrual Box ,and I want to set VPN before Tor

My last reply was the official Whonix note about front VPN
link
You look into it

You run the VPN directly on the main system and then open the VM to use Whonix.
Does that not work?

I tried it last month, no problem,then deleted it when it didn’t fit my threat model.

… I want use VPN in whonix , in main system use it is not very safe

how is it not safe in a main system? What?

My country …

and I plan change system in this years

then say that
could’ve used tails or whatever but I get it now…

oh oh
I see
