Works from firefox on windows, using your wildcard certificate

but when i put destinationUrl this https://contact.jakub1.pl

also works from widows, but is using a different certificate, is that
what you intended?

show error like this Trust anchor for certification path not found

Both those hostnames resolve to the same IP, so the client will have to support SNI to differentiate the two hostnames/certificates

You need to force add a "host:" header to the request, something like ...

val url = new URL("https://contact.jakub1.pl")
HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setRequestProperty("Host", "contact.jakub1.pl");
conn.connect();
