Hi all, After a recent upgrade to our Samvera installation, we've been dogged with "Your log-in attempt did not appear to be successful. Please try again" errors in the IIIF viewing window. When the error occurs, it occurs with everything. But sometimes everything works. I haven't been able to figure out what's making things break and work (I have no previous experience with this viewer) -- any pointers to where I should be looking would be appreciated. Thanks, kyle
