I have website supporting integrating to commertools and just today we got "502 Bad Gateway". error when accessing the site.
Our site is currently setup in AWS , dockers as containers for services.
based on AWS logs we have certificate expired error in connecting to Commercetools endpoint.
The support provided as instruction update your SSL to at least version 1.1.0 of OpenSSL and do you have the ISRG Root X1 certificate in your "trust store".
This is our first time to encounter this. We tried generating new csr using OpenSSL 1.1.1 machine but don't know how to ISRG Root X1 in trust store.
I am not sure on trust store as well.
What distribution of Linux, and what version of that distribution? You may need to continue working with AWS and/or commertools support to figure out the answers to these questions, and how to upgrade your instances to a recent version.
