Hey, what should I do to get rid of “Unexpected Internal Error (-31600)?

I am using QuickBooks online since 2 years and never had such an error popping up. I sign in to QuickBooks mostly from Google Chrome or Mozilla Firefox and I have the same error on both. Going with a suggestion from one of my officemates I restarted my computer in order to get everything refreshed. I still have the same Error Code 31600 in QuickBooks and I can’t figure out why? Everything else works absolutely fine through my browsers. A Quick solution is welcome, Thanks.
