Yes — if a Roblox join link was regenerated , the old link usually stops working, so you need the new link to join that private server. Roblox private server links can be regenerated to disable the previous invite, and the old one may expire or no longer open the same server.

What to do

  1. Ask the server owner to send the updated link.
  2. Open the new link directly in Roblox or your browser.
  3. If the link is for a private server and you still can’t join, check that:
    • the server is still active,
    • the server isn’t full,
    • you have permission to enter it.

If you mean a public server

For public servers, the direct join link only works while that exact server instance is still alive. If it’s been regenerated or the session ended, that old link won’t take you back to the same server.

Mobile note

Some players report that Roblox join links open more reliably in a browser that handles deep links well, while others may fail in certain browsers or apps. That’s why the same link can seem broken on one device but work on another.

TL;DR: a regenerated Roblox link usually means the old one is dead, and you need the fresh link or a new way to join that server.
