sys-whonix can't connect Proxy VM (use lantern proxy software)

I live somewhere that the goverment don’t allow use tor ,so i use proxy software to connect onion network and break the net block.I use lantern (proxy software ,proxy port :127.0.0.1:8787).So my network is :sys-net -> sys-firewall -> my Proxy VM -> sys-whonix -> anon-whonix. I setup lantern in my Proxy VM between sys-firewall and sys-whonix,but sys-whonix seems can not connect network through Proxy VM,when i check tor connection use sys-whonix system-check,it shows:
ERROR: Tor Bootstrap Result:
Whonixcheck gave up waiting after 120 seconds.
Tor Circuit: not established

my Proxy VM can connect the network ,but sys-whonix can’t .
My Proxy VM ip:10.137.2.17
My sys-whonix ip:10.137.5.10
sys-whonix ping 10.137.2.17 it shows:

Proxy VM ping 10.137.5.10,it does’t connect.
So :HOW TO USE lantern proxy software IN PROXY VM TO LET SYS-WHONIX CONNECT ONION NETWORK ?what about other proxy software ?Is there a tutorial for us to use lantern in Proxy VM to let sys-whonix connect onion network?
Anyone will help me ?

Debugging advice:
Remove Whonix from the equation. Learn the following first,
sys-net → sys-firewall → my Proxy VM → Tor.

(As per Free Support for Whonix ™)


Also the following documentation applies to a lesser degree.


The last link being the lest theoretical, most practical. In essence, if latern is listening as a local proxy on 10.137.2.17:8787, you need to configure /etc/tor/torrc on Whonix-Gateway to use it.

Another option that may be simpler and more common, just use bridges.

Yet another option would be to run latern inside Whonix-Gateway. Although that would be a security disadvantage. (Installing third party software directly inside Whonix-Gateway.) And also this should not really be necessary.

Needless to say, all of that - besides using bridges - is unchartered water.

I have read all your reply,and do what the link say ,but it returned
ERROR: Tor Bootstrap Result:
Whonixcheck gave up waiting after 120 seconds.
Tor Circuit: not established
Bootstrapping 80 % done. Tor reports: WARN BOOTSTRAP PROGRESS=80 TAG=conn_or SUMMARY=“Connecting to the Tor network” WARNING=“Connection timed out” REASON=TIMEOUT COUNT=18 RECOMMENDATION=warn HOSTID=“18B160CD5E22BFC345AEE7BA84B7EA45BF457FCA” HOSTADDR="85.144.162.100:443"
and now,what to do?you know ,i do not know much about network

In Lantern ProxyVM i use rinetd ,let lantern listen 0.0.0.0 :12345,in sys-whonix ,torrc set:HTTPProxy 10.137.5.1:12345,but it does not work

i know how to use bridges ,and it works ,i just want to know if there exist a way to let all the proxy software like Lantern can work in Proxy VM,and proxy the sys-whonix

What about that?
