Fourth, let's verify account information and access permissions by logging in to your account outside of the software. If you're able to sign in to your account, let's review the Bank Feeds log files. This way, we can check if there are connection failure messages to address them with your bank.
Fifth, let's test the results on the Classic (Register) mode to help isolate the issue. This is also required to use for statement download or import. Here's how to switch it in the Classic (Register) view:
Go to the Edit menu at the top.
Select Checking from the left menu, then click the Company Preferences tab.
In the Bank Feeds section, choose the Classic Mode (Register Mode) radio button.
To help fix the issue, let's enable the TLS 1.2 Security Protocol if available. Here's how:
Open Internet Explorer 11 and make sure you have the latest version installed.
Go to the Gear icon on the upper right section of Internet Explorer.
Go to Internet Options, then choose Advanced Tab.
Scroll down to the Security section.
Uncheck the USE TLS 1.0 and put a check in USE TLS 1.2.
After an hour on the phone with Chase bank, they said problem not theirs. They gave me an 866 # to QB and after waiting about ten minutes on hold a lady came on the line and listened to my story. I gave her control of my computer and she tried the QB version to get on, failed. We tried the download version, for some reason that failed, too. My lady conversed with others on her end and tried another approach. Still no progress. Once again let's try activating the download, but from outside the QBs. That worked. I have to open up and download my accounts, save to a file and then import into QBs. It's a workaround until Chase and QB figure out the problem. Chase can download to QB but it will not import on it's own. QB can download but will not import. We have a stand off.
I appreciate you for sharing your workaround in handling the Error OLSU1013. This will probably help other users that are experiencing the same error as you do.
