Verizon Messages Request Failed

[c4400]

Has anyone experienced this using Verizon Messages? Nobody can seem to figure out what's causing this. I have the app installed on the phone, and am subscribed to Integrated Messaging. The app works on the phone, syncs all messages, but when I try to use the web interface after I sign into my Verizon account, I get, "Your request has failed. Please try again later."


I've uninstalled/reinstalled several times, unsubscribed and re, did not help. Anyone experience this and/or know what causes it? Its been days and Verizon Support still has no answer. Thanks.
