I had the exact same issue with the android Airbnb app. Wi-Fi name and Wi-Fi password were already there when I run the test (configured beforehand from the PC Airbnb website), and they were definitively correct (visually at least, no typo or lowercase/uppercase errors). But after reading this thread, I had the idea to remove Wi-Fi details, run the test again which prompted me to re-enter the Wi-Fi details, and it worked this time :)) ... Maybe something to do with some invisible characters !?!? Try it, it might work for you as well 😉
