Stuck on Sending Stage (METASPLOIT)

Hello,

i had managed to backdoor a payload with another .exe template using Veil evasion with the backdoor factory method.

Now however when i execute the payload in my virtual machine, the exploit would suck on sending stage for ages with no meterpreter session popping up.

the payload is embedded in the spider.exe file, and i had closed the application after losing any hope of getting a meterpreter session ( i've waited for 10 mins ). and even had tried to embed the payload with another .exe template but nothing is working.

How can i fix this?

Thanks
