Please see the documentation - if you prepend and append a / then the value is treated as a regular expression. You need to create a regular expression that matches your two hosts.

@spinscale

is linke this http.cors.allow-origin: /https?://localhost(:[0-9]+)?/http?://xxx.xxx.xxx.xxx(:[0-9]+)?

try something like https?:\/\/(localhost|otherhost.org)(:[0-9]+)? (fully untested, you should go with some regex tester first and then see if the regex is doing what you expect)

thanks.
this slove it.
