I re-installed BTCPay Server then had no funds in my on-chain wallet or lightning wallet.
In BTCPS my onchain BTC wallet has an Action to Rescan Wallet for Missing Transactions. This worked.
In BTCPS I do have my LND hub seed words but there is no equivalent Rescan for the BTC-LN wallet. The BTCPS automatically finds my LND hub under Public Node Info but the BTC-LN wallet is empty.
Any suggestions on how to recover lightning funds?
