Tailscale and cloudflare warp

Hello,
I'm with an issue that is driving me crazy as I'm unable to solve it or figure it out why it's happening on the first place.
I have two GL.iNet routers, one acting as a server for tailscale, and another one that is acting as travel router. Everything seems fine, I can connect to it, navigate, and do all sort of stuff as if I was on my home network. However, I have a problem when connecting cloudflare warp on my computer, as I get the following error in Cloudflare warp

Status: Unable to Connect
Error reason: DNS lookup failure
Error code: CF_DNS_LOOKUP_FAILURE
Error description: WARP is unable to resolve hostnames via its local DNS proxy. Try to verify your DNS connectivity or contact your administrator for assistance.

It only happens when using it with tailscale. If I deactivate tailscale on the travel router works fine and if I connect directly to the server router it also works fine, so not sure what am I missing on the setup to ensure that cloudflare warp works as well.

Thank you!
