Has anyone come across the below?
Edition: enterprise
Version: 10.0
Contract number: M1612302628828
Click Manual Update in Online Synchronization. Tries to connect and give 504 Error. See this screencast link.... \https://drive.google.com/file/d/1SqRhTavvLgYRxvniH3PIJ1N6l8Ssyivc/view
This has happened before and has fixed itself, but this time it has been 4 Days and I can't get my Bank Accounts to Sync.
504 error actually occurs between servers, when the first tries to connect to the other and takes sooo long. You may try to check that your second server is working properly first.
