Is Vanguard OL-295-A and Error 16503 due to the 2/20/2025 phaseout of a proprietary protocol?

@heimbig I don't think you should need to restore from a backup that's month old. On the Mac side, and I think this is the same for Windows, you need to connect to "Vanguard" and not "Vanguard — Personal Investors". The former offers Direct Connect while the latter does not.

I don't know the exact terminology Quicken Windows uses. I'm saying you need to go to the account settings and remove the setting for it to download transactions. In Quicken Mac, that button is called is "Disconnect Account" and "Connect Account".

heimbig

seems to work - but it still uses web connect and downloads and uses "positions and Transactions" EXCEPT 1 of 5 investment accounts - it does positions only.

@heimbig Did you disconnect ALL your Vanguard accounts from downloading, then reconnect them? If so, you may need to reach out to Quicken Support, as I have no other insight or suggestions about why four of your accounts are using Direct Connect and one is apparently using EWC/EWC+.

To confirm: Disconnect/Reconnect is QMac terminology that is the equivalent in QWin of Deactivate/Reactivate. (You are posting in a QMac thread so the terminology used in many of the posts will be more applicable to QMac than to QWin.)

Also, yes, please do make sure that you have deactivated ALL of your Vanguard accounts before you attempt to reactivate Vanguard as recommended by @jacobs.

Then, BEFORE reactivating (but after deactivating), for each Vanguard account: Go to the General tab of Account Details and make sure "Complete Tracking" (transactions details) is selected and then click on OK. (Simply getting DC set up, again, will not make this tracking method change for you.)

When you are ready to reactivate:

• DO NOT USE Set Up Now. Set Up Now will default to the EWC+ connection method and will switch the accounts back to Simple Tracking (which shows positions and values but not transactions).
• DO USE Add Account (in the Tools menu) or the "+" symbol at the top of the Account bar on the left side of the screen. This will default to the DC connection method which supports Complete Tracking.

March 28th - Error 16503 is showing up AGAIN from Vanguard while trying to download transactions into Quicken for Mac. This occurred in February 2025 and it took 3 weeks for Vanguard to resolve. The same error code is back and curious how long this will take to resolve? I don't have this issue with the other financial institutions (6) that I work with and if it continues, I'll have to consider moving assets cause this is very disruptive!

Hi All,Im getting the error message 16503 from Vanguard and my accounts will NOT connect.

Has this problem resurfaced after the most recent fix?

Any estimated time to fix?

Broke again for me too with error 16503. Also submitted a report from Quicken itself.

Andrew Dubin

I removed all Vanguard accounts and then added using the simple tracking method. The accounts were added and each account agrees my Vanguard online information.

Unfortunately, I can only see number of shares, ending price and value. Vanguard doesn’t allow for detail tracking 😥

@Andrew Dubin That's because you switched to simple tracking. If you wait until Vanguard re-enables its server for Direct Connect you will be able to download transactions, but you'k need to disconnect and reconnect.

Vanguard fixed the problem for a few weeks in March 2025. But it is once again broken (since 3/26/25). This is excruciating!

blmatthews

And now E*Trade is broken in the same way 😥

I have not had your experiences with Vanguard. I don't call often but when I do, they are very responsive to me. I am not sure but I was under the impression that they have different divisions that you calls go to based on you account assets level. Quicken does the same thing based on the price of the product you purchased. When I called Vanguard about the Quicken issue a few weeks ago they were helpful in giving me all the details about what was going on. He told me it was being worked on but no ETA at that time. That was the same thing Quicken had said. He and I talked for quite a while about what they were trying to do for higher security and that they would get it fixed. Within about a week of that phone call everything was working again.

I hope you get your issues resolved. I have another friend that doesn't usually have problems, but is having some download problems with Vanguard right not (4/1 and 2) that are not happening to me. He may need to download the new update. I usually wait a few days before I update because sometimes issues can arise. I noticed that they came out with an update on the 1st and again the 2nd. I usually wait until there are no new updates for 6-7 days and then I figure they have a stable version.

blmatthews

Just an FYI, Quicken has released an update that fixes the Vanguard problem (for me at least). An update now updates Vanguard (including the transactions from the end of last quarter).

Andrew Dubin

Quicken's latest version, 8.1.2, has fixed the issue for me. I can now get detailed transactions from Vanguard.

Fyi…to get detailed transactions I need to select "Vanguard" (NOT "Vanguard - Personal") when adding a financial institution.

Update on previous post on 3/29/25 - Quicken pushed out an update (4/7/25) for Mac users today to address the Vanguard connectivity issues. I installed it and was able to update all Vanguard accounts again. Hopefully, this is the last service disruption for Vanguard downloads to Quicken!
