Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
The browser profile is not the one where Phantom was installed or unlocked
Extension permissions, pop-up behavior, site access, or browser privacy settings are blocked
Another wallet extension, ad blocker, privacy tool, VPN, or security setting is interfering
A connected Solana app session is stale or requesting the wrong wallet account
The extension or browser needs an update from the official source
A fake support site is asking for recovery words to reconnect or validate Phantom
A Phantom restore can show a different Solana address or incomplete asset view when the browser profile, account order, mobile backup context, hidden tokens, NFT filters, or Solana indexing state differs
A Phantom browser, extension, or mobile update can reload the wallet, reset connected-app sessions, or show stale Solana token and NFT data until the app refreshes
