Hey ​@dpsmonarch , thanks for flagging this!

Here are a few common issues with domain connection that you may want to consider:

• Cloudflare domains: If Cloudflare is your provider, you need to set the proxy status for the domain to DNS only. This configuration is required to successfully verify the domain.
• DNS propagation delays: Changes can take time to update. If you think this might be the problem, we recommend waiting a while and checking back later.
• Incorrect record types or values: Ensure the provided values exactly match what’s required. Even a small typo can interrupt the process. Figma will display an error icon if one or both of the records can’t be verified.
• Conflicting DNS settings: Check for duplicate or conflicting entries in your DNS settings. For instance, multiple CNAME records for the same subdomain.
• Awaiting SSL certificates: Figma automatically provisions SSL certificates for custom domains, which ensures secure HTTPS access, but it can occasionally take longer than expected.

Hey Celine,

I am not trying to connect to a custom domain, just editing the subdomain for the already built in .figma.site domain system.

Thanks for the clarification!
Hmm it looks odd  Can you please submit a bug report here as mentioned? Please also share in the form the URL of your file and grant can edit access with support-share@figma.com .
I’d like our support team to take a closer look at your case! Thank you
