OL-297-A error

Question

I am getting an OL-297-A error with all my accounts. They are different FIs. Quicken is updated. My computer is updated. I have restarted everything. I can connect directly to my FIs outide of Quicken. I have run through the "Error When Using Online Services: OL-297, OL-296, OL-295 or Unable to Establish an Internet Connection" suggestions from Quicken. Any thoughts? 
 Update: I noticed that the info in my accounts was very wrong. I opened Quicken from my latest backup and everything works fine. My FIs now update. Any ideas why Quicken would have started with old information instead of the current?

With OL-297 problems the most common cause is that something was 
blocking Quicken from connecting to the Internet.  If it happens with 
just one account it is usually something at the FI that caused it.  If 
it happens to all accounts it most likely was an Internet connection 
issue, a server outage or a firewall.
But, the fact that 
your accounts data was very wrong makes me think that perhaps your data 
file was somehow corrupted which can also cause connection issues.  Good
 thing you had a recent backup file.
