Does anyone else use Dynamic DNS feature?

I've been using it for a few years, and recently saw the following in my logs:
user.err ddns-scripts[11182]: glddns: cURL Error: '6'
daemon.warn dnsmasq[14661]: Maximum number of concurrent DNS queries reached (max: 150)

The reason I was even looking at logs is because of serious network problem that have been esacalating over the past few months. I think it's been related to my router, but I can't be sure yet.

I am using the DNS, he's. At different GL.iNet routers.

But 150 concurrent queries seems very a lot.
I don't know if the message comes from the DDNS or the DNS service at the router. I would say the last one.
