But I'm now thinking the problem is not directly caused by shiny, but by the fact that upgrading shiny also upgraded httpuv and some change in this package is leading to the problem. The reason I think this is that I downgraded to shiny 1.0.5. (for which my code worked previously) but kept httpuv at its current version, and my code still has this non-working behavior described in the issue above. So I figured I post an issue here too. For the actual problem, see the link above. Unfortunately the inner workings of shiny and httpuv are beyond my coding skills, so I'm stuck. Any help appreciated.
Some of my code broke when going to shiny 1.1.0. I filed an issue on the shiny site here: https://github.com/rstudio/shiny/issues/2095
