Hello there, I'm using an own Certificate Authority in order to create certificates for intranet websites. There's a chain of trust, I always imported the public part of the ca-certificate into the phones "Trusted credentials" store of android. Then it is listed under the Users-Tab. The expected behavior would be, that the Browser now trusts the all the self signed certificates from that CA. This worked many years, however this is not the case any more. Now I get warnings in Firefox under Android, that the intranet sites are not providing a secure connection. (Secure connection failed, Accept the risk and continue) Using Firefox on an actual desktop pc however works, the certificates are still trusted, the connection is shown as secure. I wonder what has happened to the Android browser version. Is it a bug or is it a feature? Btw, googles chrome also doesn't accept the certificate any more, also says insecure connection. And on Desktop, they also work. I'm not questioning that it works on desktops. Thats's why I made all the effort to set up a local CA, to have a secure connections within my intranet. I just wonder why it doesn't work on mobile phones any more. Best regards Ben
