The error `ConnectionRateLimitReached` means that the number of simultaneous connections to Realtime has exceeded the limit for your plan.
[Realtime Quotas](https://supabase.com/docs/guides/realtime/quotas):
| Plan | Concurrent connections |
|-----------------------|------------------------|
| Free | 200 |
| Pro | 500 |
| Pro (no spend cap) | 10,000 |
| Team | 10,000 |
| Enterprise | 10,000+ |
### Example:
On the Free plan, if you reach 200 channel subscriptions, whether from 200 users on one channel or 200 in total spread across multiple channels, adding a 201st will trigger a ConnectionRateLimitReached error.
### How to fix it
Upgrade your plan to allow more concurrent connections or pace the rate that individual users can join channels.
