Hi guys , im having a problem where my old router can use the No-IP dns easily.
But not sure why, the FX3060V provided by unifi is having issue.
After i key in everything, it will just stay at updated succesfully. But didnt connect. it just stays there after multiple restart.
i tried connecting the dns, doesn't work

You can prolly get better answers in related subforum https://forum.lowyat.net/topic/5458877 or general IT network main forum.

But I know that those in serious network stuff will often ditch Unifi gear as their pretty POS unless you can flash custom ROM.

Login to your No-IP account to check if it was sync and updated. Suspect the firmware loaded on the Unifi provided router, it is not enable the feature. Last time, I have similar issue too with TM router, so at the end I have to buy my own router. Now no longer using DDNS feature on router coz I hosted whatever needed on free VPS.

weirdly enough , the no-ip there can detect the ip changes. but when i try to login from outside, can't reach . even DMZ also can't reach using ddns.
use direct IP also can't @@

what's a free VPS ?

There is a firewall feature in the router, I believe it is blocking. Turn it all off.

manage to connect adi haha, but still abit cacat. suddenly can suddenyl cannot XD

Sound weird.
