Hello!
Tell me pleasy, what configurations are needed on the Reverse Proxy server (specifically, Web Application Proxy) to ensure correct access for external clients using Skype for Business? Currently, rules are set in Path Through mode, directing all traffic to HTTPS on port 443 and forwarding to the internal server on port 4443, but clients are unable to connect. What could be the potential issues causing this problem?
