Cant upload PHP file in My image (nibbles) "Connection interrupted"

Hello,

In the upload reverse part shell i cant upload any php file in the plugin my image.

I have googles every walktrough but this failure is not part of the machine.

Try reset and spawn new machine didnt help.

There is no error coming up only a " Error: Connection interrupted" and the php file didnt upload.

Also the Metasploit exploit tells me:

[!] This exploit may require manual cleanup of ‘image.php’ on the target
[*] Exploit completed, but no session was created.

can anyone help me with this ?

Thanks !

solved:

Dont have an active VPN connection on your HOST machine.
