Let's encrypt is phasing out their certificate cross-signing that allowed Android Devices prior to 7.1.1 to establish TLS connections.

They've announced that it will phase out begining Feb 8th, 2024.

This will result in a java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. exception for every domain that renewed their certificate after that date or creates a new one.

We need to change to a trust store that trusts ISRG Root X1.
