Error 350 means the bank connection has expired and needs to be refreshed. This is a normal part of how bank feeds work, as most banks require QuickBooks to re-authenticate periodically (every few months, depending on the bank's own security settings). The issue you're describing, where the connection drops again within hours of reconnecting, suggests something is preventing the connection from sticking after you re-authorize it.
Step 1: Reconnect and update the bank feed
- Go to All apps, then Accounting, then Bank transactions.
- Find your Chase account and select the Reconnect or Update option.
- Sign in to your Chase account when prompted and authorize the connection.
- Check that transactions load into the For Review tab before closing QuickBooks.
Step 2: Check Chase's side
If the connection drops again quickly, sign in directly to your Chase online banking and look for:
- Any security alerts or new authorization prompts that weren't there before.
- Recent changes to your Chase account security settings (some settings can block third-party connections).
- Any Chase maintenance notifications.
If you have multiple Chase accounts connected, try connecting only one at a time to isolate whether the issue affects all accounts or just one.
Step 3: Contact QuickBooks Live Support
If the connection consistently drops within the same day you reconnect, this is the point to contact QuickBooks support. They can look at the specific connection type used for Chase and may be able to switch your connection to a more stable method, or flag it for investigation if there's a known issue with the Chase bank feed.
While you're waiting for a resolution, you can keep your records up to date by manually uploading transactions from your Chase statements (CSV or OFX format) via the upload option on the Bank transactions page.
If the connection drops again after trying these steps, reply here with how quickly it disconnected and whether you saw any error code beyond 350. That will help narrow down the cause.
