diamond fails to run at boot with "Name or service not known" #751

On CentOS7 using diamond-4.0.515 with the included systemd service file, diamond always fails to run at boot but starts fine by a hand later.

The error in the log is:


[2020-10-23 16:07:50,198] [MainThread] Unhandled exception: [Errno -2] Name or service not known

I tried adding the following to [Unit] in /etc/systemd/system/diamond.service but it made no difference

After=network.target

I then changed that to the following and it did work:

After=network.target remote-fs.target nss-lookup.target
