I've had an older Accenture 401k in Quicken for at least the last 8+ years as it transitioned from Hewitt over to Alight. It's been working great until about one month ago when it just stopped working and nothing I do can make it work.
If I try to update transactions on this account it immediately fails with "An error has occurred" and gives me an OL-220-A error. If I try to reset the account it also immediately fails and says "Quicken could not complete the account reset." If I try to delete the connection information and enter it again, or add a new account for Alight, it similarly fails immediately. That one says "Sorry. We encountered an error. (It's not your fault.)"
I'm entering in the login info in the proper format - username-companyID and password (nothing has changed here). I can login to the website with the username and password without any issue.
Is anyone else experiencing this or does anyone have any thoughts on how to fix this? Manually updating the transactions and fund prices is getting old.

Using Quicken Premier for Windows R38.30 Build 27.1.38.30 on Windows 10.
Thanks in advance!
