An error has occurred when I ran `nimble publish`

[chocobo333]

Hi. I am beginner of nim and english.

I ran 
    
    
    nimble publish
    
    
    Run

and then an error has occurred. 
    
    
    Pushing to remote of fork.
           Info Creating PR
    httpclient.nim(271)      httpError
    Error: unhandled exception: Connection was closed before full request has 
been made [ProtocolError]
    
    
    Run

Please tell me why the error occurred, and how should I do.

Should I run `nimble publish` again?
