Subdomain approve issue


I’m encountering domain approvel problem when using subdomain.

For example;


Check the value of your twitter:domain meta tag if you have one. This should be set to a URL such as “” rather than the title for your domain.


it didnt has twitter:domain tag, i added it to Problem is not resolved.


The team has pushed an update to fix “invalid domain pattern” issues. Please let me know if the issue still exists.


Issue is still exists. I’m getting,

* whitelist request failed
ERROR: Invalid domain pattern


Sorry for the back and forth. I whitelisted the domain.

Can you send me an example URL for me to test with? Also, what Cards are you trying to approve?
