I have created a certbot certificate by folllowing the tutorial on this website, it is recognized by "https://www.digicert.com" and "https://www.ssllabs.com" but not the android manager app, I get this error when clicking on start :
Server connection failed
W/StartFragment: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
Note : The website works just fine in the same android via chrome navigator, and it says "Connection secured TLS 1.3".
I believe this is expected.
So Android 5 and 7 are just old !
Thanks for your quick answer :)
