Players can't join / PIN problems
A step-by-step checklist for when one player — or a whole room — can't get into your session.
Most join problems come down to one of a few things. Work down this list and you'll clear nearly all of them.
If one person can't join
- Check the PIN. It's the single most common cause — have them re-read the current PIN from the main screen and re-type it carefully.
- Right address. Make sure they're at tikroo.com/join, not a search result or an old bookmark.
- Connection. A weak signal can stall the join. Ask them to switch between Wi-Fi and mobile data and try again.
- Nickname taken or blocked. If their nickname won't go through, have them try a slightly different one.
If the whole room can't join
- Is the session still live? If you restarted or re-presented, the PIN has changed — everyone needs the new PIN on screen now.
- Read the PIN and URL aloud. A surprising number of "it's broken" moments are a mis-heard digit.
- Venue network. Some corporate or school networks restrict browsers. If Wi-Fi is the problem, ask players to use mobile data.
PIN keeps showing "invalid"
An invalid PIN means the code doesn't match a live session. Causes:
- a typo (re-check every character),
- an old PIN from a previous session, or
- the session was ended — start presenting again and share the fresh PIN.
Still stuck?
- Have the player refresh tikroo.com/join and start over.
- Confirm their browser is current — see Supported browsers & devices.
- If they were in and dropped out, that's a reconnect case: Reconnecting.
