Publishing to Gradle Plugins Portal

I was prompted to add a TXT entry in the DNS system to confirm domain ownership, so I added the ‘gradle-verification’ record to our DNS. Although this record exists, my publishing attempts are constantly rejected with the message that I should add this record. But it does exist! Something is wrong here, but there is no support I can contact. It seems that the validation process is fully automated. Does anyone have any idea how to resolve this situation?

Sure there is support.
You can for example open a ticket at GitHub - gradle/plugin-portal-requests: Gradle Plugin Portal issues and requests. or write to the e-mail address mentioned there.
