AWS libcrypto resolve messages seen when using a boto3 library, apparently after an update

I'm using the s4cmd package in Python which in turn uses boto3 to communicate with a (non Amazon) S3 service. I've started seeing these warning messages on stderr. I believe this happened after an auto update to OpenSSL, but that's just my best guess.

Does anyone know what these messages are, if they're ignorable, and if they are how to suppress them? The onset of these messages correlates with a lot of random SSL failures. Both in Firefox and when using boto3. I commonly see errors like [Exception] Connection was closed before we received a valid response from endpoint URL now, but when I ssh into another server I have no problem. An hour later the problems will be gone, only to reappear some apparently random time later. **Additional info:** I recently noticed that inside a docker container on my laptop my boto3 & s4cmd commands work while they fail on my base OS. I checked openssl version on both: ``` # Base OS, failing openssl version OpenSSL 1.1.1g 21 Apr 2020 # Inside docker container, working openssl version OpenSSL 1.1.1 11 Sep 2018
