Hello, For me it seems to have been the update of ca-certificates-mozilla to 3.60 (14th Dec.) which removed some root certificates. https://wiki.mozilla.org/CA/Additional_Trust_Changes I tried manually adding some digicert CAs and sub-CAs I found with wireshark. At first it seemed to work and then suddenly not. https://cde-ta-g7g.amazon.com/ https://www.digicert.com/kb/digicert-root-certificates.htm Since then I run kindle with bubblewrap, replacing /etc/ssl/certs/ca-certificates.crt with the version from the old package. Not the best, but I haven't found a better solution yet. -- Andy
