Problems getting dictionaries for most (older?) devices

[wonczak]

On four of my mobile devices (three tablets, one smartphone) aedict cannot contact the servers to get/update dictionaries. Only my newest device is able to get a response.
The other devices give the error messages in the attached screenshots. It looks like the server does not like oldish certificates.

(Devices are one Android 4.4.4, one Android 7.0, one Android 8.0.0, and one fairly recent Android 11. Only my Android 14 works as expected)

More details available on request; I can also test.

The reason is that you're using old Aedict. the dictionaries were moved from baka.sk to aedict-online.eu; in newer Aedicts, the dictionary download link is correctly updated. The only fix is to upgrade Aedict. The easiest way to do it is to have Aedict installed from Google Play.

The newest Aedict version is 3.51.6, and that version correctly downloads dictionary files from aedict-online.eu.

Interesting. I was fairly sure that I had the newest version at least on the Android 11 tablet. It now works :-)
My oldish Android 8 phone also works now (it indeed had a slightly older version of aedict). My 4.4.4-Tablet reports "app is no longer supported", which is sad, but understandable :-)
Android 7 however, is still a bit different: I have the latest 3.51.6-version, the dictionary manager reports
"Failed to download remote dictionary listing: java.security.cert.CertPathValidatorException: Trust anchor or certification path not found"
As an aside: I am always impressed with your speedy responses!

The problem is that Android 7 only supports older https certificates which are known not to be as secure. Android 7 is unable to use the secure certificate offered by aedict-online.eu, it rejects & ignores the certificate and then fails with the above-mentioned error.

The solution is to upgrade to Android 8+ device; alternatively I can try to reconfigure the server to also accept less secure certificates but it seems rather complex: https://community.letsencrypt.org/t/letsencrypt-certificates-fails-on-android-phones-running-android-7-or-older/205686 . I'm reopening the ticket to investigate this path, but I unfortunately don't have much spare time so it may take a couple of months to take a look at this.

I really appreciate your willingness to look into this. It -might- just help others who cannot easily upgrade to a newer android device.
