Why my log file is full of this message

Technical Support for Routers

My GL-MT2500a log file is full of this message every minute: "ddns-scripts[23129]: glddns: cURL Error: '7'".
It looks like the built-in DDNS has issue, however I test it and it repots back the DNS resolved correctly.

FW: 4.7.4 stable

Hi,

Confirm that if the WAN public IP has changed, is the GL-DDNS service normal, the new IP resolve correctly?

Try disable and re-enable the GL-DDNS to see if the log will print again & again.

It happened after I upgraded the new U-boot FW, I re-flashed the FW 4.7.4 and the error messages were gone and the router run smoothly after that.
