Discord Error 2015 is a connectivity or video-stream timeout error on Discord — typically shown as “Something’s going wrong, error 2015. Please try again later.”
It occurs when Discord fails to communicate with its servers — often due to network issues, corrupted cache, VPN/proxy interference, firewall blocking, or outdated app files.
Common fixes: restart Discord and your device, clear the app cache, disable VPN/proxy, update or reinstall the app, check network/firewall settings, and ensure system time/date is correct.
