Custom domains stuck verifying

We are posting updates to https://ask.replit.com/t/custom-domains-stuck-verifying/27283 for this issue. We are working on revising our documentation to explain the limitation in better detail and are investigating mitigation long-term.

Upon investigation, we have identified that this issue is related to CNAME flattening, where various DNS resolvers automatically add an A record along with the CNAME record, preventing us from verifying the domain. We are actively working on finding a solution to address this on our end and resolve the verification issue. We apologize for any inconvenience caused and appreciate your patience as we work towards a resolution.

We are aware of the issue(s) where custom domains are stuck in the “verifying…” step and not progressing. We have identified that this is due to a change made on our end and are working towards a resolution.
