too many connections from haproxy ip

[Miguel Rodriguez]

Hello everyone.
Let me start by saying that I'm a newbie and you might find something shocking below ;-)
I'm setting up a test environment with an InnoDB cluster of 3 nodes + 2 routers + 2 Haproxy instances with KeepAlived.....

The 3 instances replicate correctly and are individually accessible, and they connect to the primary router IP from the routers.....

But from the VIP or from the Haproxy IPs, I always get the error "too many connections from <haproxyIP>."

I've googled, chatgpted, expanded max_connections_error, max_conn, max_user_conn..... and various configurations in mysqlrouter.cfg / haproxy.cfg... and I can't make any progress.

The actual threads or connections to MySQL don't exceed 5-6 using just my user.

Does this sound familiar? Can you give me some guidance?

Thanks again, everyone.
