Certain sites take forever to load while on Wi-Fi but is fine on cellular.

I have an iPhone, an Android phone, a macbook and a mac mini, I hooked them up to the same tailscale network and runs adguard home on the mac mini which takes all the dns request of these devices.

Everything worked fine until last week, whenever I tried to access twitter and reddit (these two specific sites for now, other sites seems to load very normal), it started to take forever to load on every devices, no matter on phone apps or browsers.

I have tried everything I understood, I have disconnected from tailscale, I tried changing the dns server on my router and devices, nothing worked.

The only two ways I found for it to work is if I switched to cellular or when I used the Cloudflare WARP app on my phone. However when I manullay set the dns server to 1.1.1.1, no matter on devices or router, it did not work.

What am I missing here?

Thank you in advance!
