Changed ( in source, will be in next build )
accesscode=""--> Set hostname + edit field
invalid cert: cert of sfx extractor need to be removed, you append the archieve -> crc changed -> invalid cert.
Valid certificat can only be created if archieve is signed, not the sfx part

, only possible with some online creator app
Firewall warning is issue's by the OS, can't be stopped.
Lan: if server/viewer have the same external address the internal port/address is used.
Sample
10.10.10.1 -> router -> 153.23.23.26 -> access server
10.10.10.2 -> router -> 153.23.23.26 -> access server
The access server get both server/viewer from the same origin (153.23.23.26), in this case he tell server and viewer
to use 10.10.10.x addresses to connect. This works on my home network, but seems to fails on yours.
It could be some internal security setting
Some "realtime" logging need to be added, to see what happen when nothing connects. The icons are to restricted.
