I just found this post:

Internal error doing a POST to /api/rockons/update

@k0nsl Welcome to the Rockstor community and thanks for the report. Re: So I’m assuming that all you did was press the “Update” button in the top right then? The “POST” part here indicates that the error was during an update of the database, when on occasions the server side has run out of connections we get a timeout message so I don’t think this is that. And we have made some changes in the more modern code to remove the number of redundant checks that we were making on the server side so…

I will report my update after trying what is here.
