Our root certificate for the web server expired last week and was replaced by a new one.
With the exception of the AndroidApp, everything works as expected.
The error message is: "A Server with the specified hostname could not be found"
The certificate has been issued by "Sectigo RSA Organization Validation Secure Server CA", former COMODO RSA.
Can someone help me or tell me where the error is. How can I debug the Andorid app connection if necessary.
