Power Shell will be expired after 24h about unicorn HOT 2 CLOSED

Same problem here!
I think that unicorn (created by metasploit) isn't stable and will be expired after some time!

Is there any way to use the unicorn for more time? Or any solution?

from unicorn.

This isn't a unicorn issue.

Meterpreter doesn't technically ever expire - there are time lengths where sessions will be available and are adjustable under show advanced inside of the payload (multi/handler).

If you want to look at these options just launch msfconsole then type:

use multi/handler
set payload windows/meterpreter/reverse_https
show advanced

What you could do if you want a longer period of time for the session to remain active is change the unicorn.rc file and right before the exploit -j use will want to tweak the following:

SessionCommunicationTimeout 300
SessionExpirationTimeout 604800
SessionRetryTotal 3600
StagerRetryCount 10
