I have an inotify cron(Incron) that based on some changes to a text file, it should run a script. Below is also my incrontab file
/home/pi/payload.txt IN_ATTRIB,IN_CLOSE_WRITE bash /home/pi/deploy.sh
To show that the incrontab is actually firing the script below is the log from it
Dec 23 19:17:01 raspberrypi /USR/SBIN/CRON[13526]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)

It works except that when it restarts the node server and I try to access it over web, it gives me a forbidden error like below:

This shell script also restarts a flask server but that's restarting fine. The more weird thing is if I run the shell script manually(by SSHing to the server and running ./deploy.sh), it works fine, no forbidden error. I'm just stunned as to how this could happen even though the incrontab is running the script as the same user that i used to run the script manually.
To give more info: I am running both a flask and node server using screen sessions so each server has it's own screen session. So the bash script just kills the screen sessions, pulls latest changes from my GitHub repo and then restarts the servers in screen sessions. They're both running on a raspberry pi
My last resort is using nodemon or BUT I would actually like to know why this error is occuring. Thanks!
