Reconnect the account by selecting Add Account and entering your bank credentials again.

Choose All Time in the time range.
Select Cached images and files and Cookies.

Firewall or antivirus isn’t blocking QuickBooks Online.

If you use a VPN or proxy, disable it temporarily and retry connecting your bank account.

Step 6: Run System File Checker (Windows Users)
