Wallet balance chart - 5 days behind

Today is Sept 29th, but my wallet balance chart only goes to Sept 24th
Chart is 5 days behind, but PoCr mining is up to date at Sept 29th.
Wallet: http://34.34.34.34/walletBalance

Any reason why the wallet balance chart is so far behind on the dates?
I restarted the Genisis miner, but no change.
