When you are trying to connect to the voice servers on Discord, “RTC Connecting” appears and remains all the time. You can also see a message “RTC CONNECTION, locked and loaded! Discord has established a secure connection to your real-time communication server and is attempting to send data” on the blank screen.
The voice chat on Discord is unavailable due to this “RTC Connecting” error on the Discord browser or Desktop version.
What Does “RTC Connecting” Mean?
It is known that Discord is a free text, voice, and video chatting app that is popular worldwide. In this case, “RTC” refers to Real-Time Chat protocol (or WebRTC).
Therefore, normally, “RTC connecting” means that Discord is trying to connect the voice server over which you are to communicate with your friends in forms like text, voice, or video.
However, this loop of “RTC Connecting” implies that something went wrong with the chatting protocol, which is mainly affected by the internet. In short, Discord stuck in “RTC Connecting” means that Discord cannot connect to the server due to network issues.

Solution 4: Disable Discord QoS (Quality of Service)
It is said that Discord Quality of Service (QoS) allows users to manage the available network bandwidth and make sure that important network services are given priority over less important traffic. Hence, users tend to enable it on Discord.
However, many users reported that Discord’s RTC Connecting problem will appear. Therefore, you may need to temporarily disable Discord QoS.
