Domain validation fails with "Bad Request"

I am in the final steps of validating my domains for a published Zoom application. There are two domains to validate. The first one validated without issue (using TXT method), but when I go to validate the second domain, I see a “Bad Request” popup error when I select a validation method. Then when I select “Validate Domain”, I get a full page error that says “An Error Occurred. Refresh the page and try again.

How do I get past this Zoom error so I can complete my app submission?

Hello,

Thank you for reaching out in relation to Our Domain Validation process, the next steps will be sent to you via DM. Please refer to our domain validation resource: Domain Validation Explanation for any further questions you may have about the process.

Thank you.

I have yet to get a DM from anybody about this. Any way I can get some help here?

Sorry, I was investigating trying to figure out the issue; you should have received a DM by now
