What's the maximum number of concurrent Websockets connections allowed?

I’ve received this error code after having certain amount of processes connected to websockets server:
The server returned status code ‘503’ when status code ‘101’ was expected

Is there any limitation regarding maximum concurrent connections in the free plan? What options are available to scale it?

Hi,
From what I know the limitation is in the number of requests per minute: 3600 requests per minute.
Not sure how that limitation works on web sockets. In order to scale it you can talk to Kresimir#3615 on discord.

Thanks! I’ll contact him
