Your Primary Name Missing? Two Common Causes
Weekend Updates
Etherscan sometimes run weekend maintenance that temporarily hides primary names or shows outdated ones. If your Primary Name shows on the ENS App, it's working correctly. Check Etherscan again in 2-3 days.
Primary Name also missing on app.ens.domains? Follow these setup guides: How to Set As Primary Name or Set Primary Name for contract
DNS imported names
Etherscan doesn't support DNS-based ENS names as Primary Names. Your Primary Name works everywhere else that supports ENS—just not Etherscan.
