Starting server for the first time on Raspberry Pi throws java.io.IOException error - Rouquemoute - 12-12-2020 16:57
Hi there,
Anyone successfully installed and started MinimServer 2 on Raspberry Pi ?
I get this when executing the startup script :
> minimserver/bin/startc
MinimServer 2.0.16 update 178, Copyright © 2012-2020 Simon Nash. All rights reserved.
Error writing data to license buffer: java.io.IOException: platform data error 1e
MinimServer error: now stopped, use 'restart' or 'exit'
Any hints on how to debug this ?
Thanks a lot !

Please post the output from the following Linux commands:
/sbin/ip route get 8.8.8.8
cat /proc/net/route
Which model of Raspberry Pi is this?
VPN causing issue ? - Rouquemoute - 12-12-2020 17:24
Simon,
It's a Raspberry Pi 4.
A VPN client is running on it, which is most likely the source of the problem

Thanks for the quick reply. Please also try this:
cat /sys/class/net/tun0/address
cat /sys/class/net/tun0/address - Rouquemoute - 12-12-2020 18:16
This returns nothing
> cat /sys/class/net/tun0/address
[nothing]

FYI, turning off the VPN allows the startup script to proceed.

Many thanks for your help with debugging this problem. Please also try both of these with the VPN client enabled:
ip a
ifconfig
Which VPN client is it?
