Unable to re-establish online connection to Schwab

I’ve had a Schwab account for years and Quicken has accessed and update from it during that whole time.

A few days ago it quit updating, displaying the OL-295 error message.

Following the Quicken guidance;

I’ve tried to reset the account, to no effect.

I’ve deleted the online access.

I’ve tried to re-establish online access but Quicken requires a PIN before can select “Connect”. I’ve don’t have a PIN for the account. I’ve entered 0000 or my Schwab passcode and I continue to get the same message.

I’m awaiting a reply from Schwab. Unfortunately I don’t understand why this has stopped working this week when nothing else has changed.

Any ideas appreciated?
