B4J Question can not run myapp.jar on a server

in my server (http://xxx.xxx.xxx.xxx) i can hit the api with curl and retrieved the data as shown below

but when i tried to executed myapp.jar, it shows this error as shown below:
imgpsh_fullsize_anim.png

so it seems don't support http2, so i changed it to --http1.1, but still given this error, it can not receive the data from the token, as shown below:

what got me confused it's that i can hit the api and received the data as shown above, i even using --http2 not --http1.1, but when i tried to run myapp.jar it can't receive the data from curl. but when i run myapp.jar on my local pc, it runs perfectly.

anyhow to fix it? so it can also run on my server http://xxx.xxx.xxx.xxx. i'm so confused why it can't received the given curl (api,token,etc.) when running on server, but can received the curl when run on the local. thank you so much
