Hm.. interesting failure; perhaps needs some additional error handling somewhere

FWIW; I was considering if dropping the legacy/insecure CBC ciphers should wait, but I noticed that compose already updated this dependency, and AFAIK, there's been no issue reported related to dropping those, so probably fine to include 😅
