  • Your VPN might change your IP address, causing dynamic IP, that's when Discord will experience a stuck issue on RTC connecting.

  • Your antivirus program could also identify a Discord file as a threat and quarantine it. This will prevent further connection of Discord.

Part 2. Full Guide to Fix Discord RTC Connecting Error 

Discord relies on the WebRTC protocol to execute its functions. So, before proceeding to the below fixes, ensure your internet connection is proper and functioning as desired. If it's good enough, then follow these fixes to solve discord stuck on RTC connecting issue.
