To use it with this project, add a TXT record at `_vercel.eu.cc` to verify ownership. You can remove the record after verification is complete.** system (@system) · 2026-03-01 The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you.

Pauline P. Narvas (@pawlean) · 2026-03-01 You still need to verify ownership even if it's added to the PSL I believe! Can you add that TXT record? Wyllc (@wyllwyc) · 2026-03-01 Some old second-level domain suffixes in the PSL list do not require adding TXT records; only some newly added domains in the PSL need TXT records. As a user, I actually use third-level and fourth-level domains, and I am not the owner of the second-level domain, so I cannot add TXT records for the second-level domain.
