Whenever you try to join a Discord server and a pop-up window says the Invite link is invalid, the question is how should I troubleshoot it?

Make sure the website link on the output is in this format -> https://discord.gg/abcduehfjd ✅, not as https://discord.gg/ab%cd%u%8d ❌

2. Discord sometimes behaves weirdly, so make sure you are actually logged in. If you are unsure, log out and log in again!
