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? 



The two main reasons that might cause this error are:

 

1. The invite link that was clicked on generated an entirely different kind of link: 





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, logged out and logged in again!
