Thank you so much for posting this. This thread came up in a search for “[Error: Input buffer contains unsupported image format]”. I updated my instances icon and banner photos earlier today and that apparently was enough to bring the whole thing down. I ran that command while connected to the database and now I’m back in action.

I’ve been very happy with my RB5009. I ditched my Edgrouter X because it’s not getting software updates anymore. Pros and cons to both, but Mikrotik/RouterOS is starting to make a lot more sense to me, and at this point I’m more comfortable with it than I ever was with EdgeOS.
