This means you've had enough concurrent connections to surpass your limit or hit a warning.  Connections are counted for each instance of the Ably library connected to Ably.

There are three types of connection limits you can hit:

  • connections.warning - when you reach 80% of your pre-paid quota.
  • connections.soft - when your pre-paid quota has been exceeded. You may then be charged at the base rate¬†($12.50 p/thousand) for exceeding your connection limit for extended periods of time.
  • connections.hard - when the hard limit on the account has been exceeded. You will not be able to create new connections until you're below your hard limit.

If you need the ability to have more connections, we recommend you upgrade your account.

If you're certain you shouldn't be hitting your connections limit, make sure you're not instantiating an Ably library multiple times.
