TeamSpeak 3 servers beginning with version 3.1.0 use HTTPS connections for communication with the accounting backend. The TeamSpeak 3 server can be configured to use a proxy server for the accounting system in cases where direct internet access is not available on the system running the TeamSpeak 3 server.
The proxy server is specified by the http_proxy command line parameter which accepts domain names, IPv4 and IPv6 addresses and must include the port. It can be specified in either an ini file (itself specified with the inifile parameter) or be provided on the command line.
The following are examples of valid http_proxy parameters:
The proxy provided must not require authentication, as that is not supported by the TeamSpeak 3 server.
