I have to debug such an issue some weeks ago. I got a call for help near
midnight and wasted nearly 3 hours to get it working (sort of).
Something changed between OTP 20.3.2 and 22.214.171.124 that makes some
certificates unhappy. I bypassed it by using SSL application from 20.3.2
with OTP 126.96.36.199. There is some bug somewhere.
