I’m just chiming in to say that you’re not the only one seeing this problem. There’s definitely something weird going on. I’m using Tailscale on a GL-AXT1800 (Slate AX) with Admin Panel v4.5.0 and a manually upgraded Tailscale version 1.62.0 through the script on this forum post.
I also cannot see duckduckgo.com through a browser or curl, but can ping the hosts no problem.
$ dig a duckduckgo.com

$ curl https://duckduckgo.com/
[operation times out]
However, I can ssh into my GL-AXT1800 and run the curl command just fine.
