Crash when using 443 remote port
I'm using Ubuntu 16.04.1 64 bits and Duniter 1.6.10. My pubkey is: Do99s6wQR2JLfhirPdpAERSjNbmjjECzGxHNJMiNKT3P
Actualy my node is listening the port 16262 for local and remote port. The thing is, it's not an https port so I would like to configure the 443 for remote port, because for instance it's not accessible from cesium: https://g1.citiz-network.org:16262/network/peering (change to http to access the node).
The problem is: When I try to change the port in Duniter interfacefor 443, Duniter crash and can't start again, so I have to change the port again in file configuration in ~/.config/duniter/duniter_default/config.json
Every other port are ok, but not 443. Of course I checked, nothing is using this port on this server:
netstat -pnl | grep 443
return nothing
In duniter log I only have this info when try to start the app:
2017-10-17T15:20:45+02:00 - info: Block resolution: 0 potential blocks after current#61555...
I tried to flush data and reinstall duniter, but nothing new
Do there is another place to see more error log, and did I miss something to configure my node in https ?
