Autostart after boot failing

[Gazmac52]

Hi,
I have followed the directions to start the service automatically. 
However, after reboot the status is this:

pi@irrigate:~ $ systemctl status sip
● sip.service - SIP

   Active: failed (Result: exit-code) since Sat 2019-04-13 08:59:06 AEST; 1min 8s ago

If I do this then all ok:

Any help appreciated

The error "socket.error: No socket could be created" indicates that there is already something using the default port (port 80).

Do you have another server program like apache running?

Once you get SIP to start you can change the port it uses from the Options page. Change "HTTP port:" from 80 to something like 8080. This may help.
You will then need to add the port to the URL when you access SIP for example http://x.x.x.x:8080

I have seen this happen after starting SIP manually and then trying to start it using systemctl.

Thanks dan.
I stopped autostart and rebooted.
sudo netstat -pln, nothing on port 80
started sip
port 80 now in use.
changed port to 8080 and tested ok.
set up auto start
rebooted, error still there even though now on 8080.
start sip and web page responds on 8080

I am inclined to think it is a timing issue but I don't know how to delay the service start.

I have not seen this problem before and I don't know of a way do delay the auto start.

You might try uising rc.local to start SIP even though it is not the best solution.

If I find another solution I will post it here.

Apparently you can use a sleep statement in the unit file (sip.service)

I have found an answer.

sudo nano /etc/systemd/system/sip.service

And modify like this:

[Service]
ExecStartPre=-/bin/sleep 10
ExecStart=/usr/bin/python -u /home/pi/SIP/sip.py

This has fixed it for me.

Great!

Learned a new trick today.
