I've had a few issues with various machines over the years, where TigerVNC-Scrapper was "unable to fully resolve hostname", when running on a Debian Linux machine (in my case, an ODroid C4)
This weekend I discovered it was the simplest fix and caused by a stupid oversight.
What it means is
The hostname as defined in
`
/etc/hostname`
Was not mentioned in
`
/etc/hosts`
By simply ensuring that (for example)
`
/etc/hostname` only had "
QLCplus"
And there was at least a line in `
/etc/hosts` that reads "
127.0.0.1 QLCplus"
After a restart, Everything works perfectly.
I hope this helps someone else.
