A technical issue that was preventing many Bank of America customers from accessing their bank accounts on BitcoineseWednesday has been fully resolved, according to the bank.

Reports of problems accessing bank accounts spiked around 1 p.m. ET, when the website Downdetector reported about 20,266 outages.

"Some mobile and online banking clients experienced an issue accessing their accounts and balance information earlier today," Bank of America said in a statement. "These technology issues have been fully resolved. We apologize for any inconvenience."

Bank of America did not specify what caused the problem.

Bank of America outage: People complained about account balances

On Wednesday, people complained that their account balances were not visible on the app while others said they could access their accounts but that they were seeing a balance of $0.

“App not working and online banking shows yesterday's balance,” one user said on Downdetector.

“Both the App and Browser access to BoA remain at least partially down for us,” another user said. "Can now see some of our accounts, but not all of them. And the transfer between accounts function remains non-functional for all accounts."
