Hello @barbfilk
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I was taking a look to see your recent tickets and did notice a ticket but didn't have any mention of collecting logs or escalating inside of the ticket. Generally 511's are not something that need to escalated but something that one of our agents need to change within our side.
If you have another chance here soon could you contact Quicken Support via phone and let them know you're getting CC-511 errors. They should collect your logs and work on getting it resolved within the length of that call. If they do try troubleshooting refer them to the 511 article here. You can also refer them to my community post as well.https://www.quicken.com/support/error-when-using-online-services-cc-511-you-have-encountered-temporary-system-issue-or-its
Once you have a chance to give us a call and let us know how it goes!
Thanks,
Quicken Francisco
