Join link not working for new players

no matter what i do none of my links for any of my campaigns are working at all

Sorry you're having trouble. Can you describe "none of my links are working"? Previously-sent Join links are invalidated if you Kick / Remove someone from the campaign. If you've done that recently then re-issue the new Join Link.

Can you please follow Steps 1-3, taking special care to temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, please follow Step 4 , including providing all of the necessary information, so that we can further assist you.
