QMac 16503 Error Connecting to Regions Bank

ThomasM

I have been having issues with Quicken Classic for Mac and Regions Bank for almost a week.

On Saturday I was getting a 15500 log in error. I was able to log in to my Regions online banking account with no issue, so I knew it was not an issue with my username or password.

I tried following some advice on another thread about disconnecting the accounts and deleting the Quicken password from my login Keychain on my Mac (I am on Sequoia 15.4.1 running the latest Quicken 8.2.0). This did not work at all. In fact I think it made the issue worse because then I couldn't log into my Regions account through Safari anymore. The Regions website was saying that the page could not be found. It did not say my account was locked or anything of that nature and I did not get any text alerts or emails about my Regions online banking account being locked.

I downloaded the Regions App for my iPhone to see if I could log in to my Regions online banking account through the app (which I have never used) and the app said my password was invalid. I use the app to re-set my password. After re-setting my password I re-connected my accounts in Quicken and entered my new password and was able to successfully download transactions yesterday.

However, today when I tried downloading transactions, I am getting Error 16503. See screen shot.

This has GOT to be a Regions issue right? I am on a text chat with them now and they seem clueless. They say I have to call their online banking department during business hours (at which I am at work and away from my Mac).

Hi @ThomasM ,

Did you happen to update to Sequoia 15.5 yesterday? I think I had the Regions update on my mac Quicken give me the error once on Saturday but then worked. Now, it won't get past the error.

My iPad and iPhone apps work fine.

I tried the support article idea that @Quicken Anja put up and it didn't change anything. I already had bank bill pay enabled.

Any other Regions users on Mac having this issue?

Hello @gronesy,

Thank you for taking the time to add to this discussion.

Just to confirm—do you also have Bill Pay enabled on the Bank's end? Or just in Quicken?

Thank you!

Thanks for the advice Quicken Anja. I just launched Quicken on my Mac for the first time today. There was a banner at the top that said it could not connect to my Regions accounts. I clicked the "connect" button on the right side of the banner and it was able to connect to Regions and download all my transactions. I am not sure why it worked today and did not work yesterday. I have not updated Quicken nor have I updated to MacOS 15.5, so in other words, nothing has changed with my system, so something must have changed either with Regions online banking servers or with Quicken's servers. That would be just a guess though. Either that or this is a sporadic problem, because as I stated in my OP, I had issues Saturday (but with a different error code) and then it worked briefly after re-setting my Regions password only to have a connection issue with the 16503 error code on Sunday. I am keeping my fingers crossed that this doesn't occur again!

Also, I did read the article you referenced concerning bill pay. I noticed bill pay is turned on in Quicken for all of my Regions accounts. I toggled them off and the logged in to my Regions online account to see if bill pay was turned on. Unfortunately, their website is rather confusing when it comes to bill pay. I have the option to pay bills through Regions website (and app) but it doesn't appear that it is active (at least I don't have anything set up currently to be paid through their bill pay option). There is no toggle on/off for bill pay on their website or app, so if any Quicken user can provide some guidance on what I need to look for on Regions website to tell whether or not bill pay is active, I would appreciate it.

Hi Jeff,

I have not updated to MacOS 15.5 yet. See my reply to Quicken Anja for more info.

At this time, I am able to connect to Regions from Quicken and download transactions successfully.

Keeping my fingers crossed that this will not occur again. I have had connection issues between Quicken and Regions in the past but they usually resolve themselves in a day or so. Perhaps I was a little too impatient this time, but for the money that Quicken costs me annually I expect it to work as advertised!

@ThomasM Thanks for the update! I'm glad to hear that it is working now.

Should the issue return, please don't hesitate to reach back out.

Thank you!

Well here we go again. After working for a week I am now back to getting the 16503 error. What is going on?! I am so frustrated. I pay Quicken enough money per year for this software and it seems like they don't fix these errors in a timely manner!

PS - I did just update to the latest Quicken Classic for Mac 8.2.1. I sort of wish I would have tried downloading my Regions transactions BEFORE I updated to see if something the the update broke the connection to Regions.

I don't think you are allowing for the fact that most connectivity problems are caused by the financial institutions changing something which breaks Quicken's connectivity; then Intuit (Quicken's connectivity service provider) needs to make changes to catch up, or to reach out to the financial institution to get them to make changes to fix the problem. It's possible, but unlikely, that Quicken made some change which broke the connectivity. (Of course, Quicken never publicly states what the problem is, because they don't want financial institutions to get mad at them and decide to stop supporting Quicken.)

I updated to Sequia 15.5 yesterday. Last week the download from my Regions account worked just fine, today I, too, get the 16503 error. I have used bill pay from Regions for years. I do not use bill pay from Quicken.

I'm running Sequia 15.5 and Quicken Version 8.2.1 and having the same problem. Error code 15603.

I too am running Mac Sequoia 15.5 and Quicken Version 8.2.1 and having the same problem. Error code 15603. I have attempted to connect and disconnect the account. I am no longer able to connect.

When I try to re-connect I see the following error message.

I have the same Error code 16503 and have not updated to Sequoia yet. The Regions connectivity errors just started this weekend. I don't think my error is caused by not updating to Sequoia, because my Quicken is running with MAC OS 14.6.1 . I can sign into Regions on my MAC via Safari so I don't think its is a Regions issue. I tried to reset up my download but cannot connect to Reions to do that. Any other ideas? Thanks

It seems to be working for me now as well. I really wish Regions and Quicken could work more closely together to prevent this from happening so frequently. I am sure this is something Regions is doing on their end and the Quicken team has to play catch up every time Regions changes settings on their servers but this is very frustrating!

jamiekdavidson

It started working!! But based on the above I may hold off on upgrading to Sequoia

@jamiekdavidson I don't think it has anything to do with which version of macOS you are running. Almost all connectivity issues are at the server level, and are resolved by the financial institution and/or Quicken's connectivity provider (Intuit) applying a fix. You may note that whatever fixed the problem yesterday did not require either a macOS update or Quicken program update.
