Several thousand Fidelity Investments clients reported problems accessing their accounts online and through applications like Active Trader Pro Wednesday afternoon, during the market's final trading hour.
At the time, the giant financial services company said it was "working urgently" to fix the trouble.
Downdetector, which monitors financial institution and internet outages, showed 4,208 problem reports for Fidelity around 3:40 p.m. EDT. The baseline for the number of Fidelity trouble reports is three, the site indicates.

"We are aware that customers are experiencing issues with Fidelity.com, Active Trader Pro (ATP), and our mobile apps. We are working urgently on a resolution. We apologize for the inconvenience and appreciate you being a customer," Fidelity tweeted at 3:45 p.m. EDT and repeated in response to client complaints on X, formerly Twitter.
The problems seemed to be resolved about an hour later.
Shortly before 4:45 p.m. EDT, Fidelity explained in a tweet: "Thank you for reaching out. There was a temporary issue impacting Fidelity's online platforms today, August 30. All systems are now up and running. If using ATP, please restart the application. We apologize for any inconvenience."
Clients on Downdetector said earlier they could log in but their trading accounts showed no positions or their accounts appeared to be "hidden."
