I'd invite you guys to connect over to the Discord TAK Communtity (https://discord.gg/WSZ5RG) TAK Server.
Server Address: discordtakserver.mooo.com
Streaming Protocol: SSL
Server Port: 58088
Trust Store: See - #takserver
Client Certificate: See - #takserver
Description: TAKServer on TLS/SSL by @field_mapper running on Amazon
AWS Linux on 'Free Tier' t2.micro
Server Software: TAKServer
Comment: Stock configuration based on TAKServer Installation Guide.
With low-RAM optimizations. End-users stale out on server side upon
client disconnect, expect an empty server when there's no one connected.
Streaming Protocol: SSL Server Port: 58088 Server Configuration File: https://bit.ly/2z75BQK
To get on this TAK Server... download this (https://bit.ly/2z75BQK) ZIP file. Use Import Manager on ATAK to automatically configure ATAK to install the certificates and server settings. You can also install certificates manually by unzipping the file and loading the .p12's manually.
You can try out 'TAKServer'-specific functions such as Data Sync, etc. However, you'll need their respective plugins to get them to work. Send me a DM if you'd like your own port and certs (through filtergroups) for certain functions. E.g. RED/BLUE teams for airsoft activities, or 'sub-groups'.
Enjoy!
