RegEx at Layer7

I’m trying to use “.tld$” (without quotes) regex for selecting top-level domain at layer7, but Mikrotik doesn’t understand it? How should I fix it?

Doesn’t work for me. I need to find domains like “.local”, I tried:

local$
.local$
local\$
.local\$
"local\$"
".local\$"

No chance.

why not add them via winbox?

Already tried the same variants as at previous post.
