I yesterday bought new android phone.Many HTTPS ( like Primegrid) works OK, but for Top 5000 primes page I got error: Your connection to this site is not private.
That is very weird since on same time , on same WIFI network with WPA-PSK2 encrypted Primegrid page is not show that problem.
I also try Firefox for Android, and got same error.
Does anybody knows what is heapen?
Since I am sure , many of us here same Android phones it is easy to check behavior in Chrome.
Thanks for any info

I can confirm when visiting https://primes.utm.edu/ I get that message on Chrome on Android, but I don't get that message with Chrome for Windows. Same internet connection. Adblock Browser on Android also doesn't report any error. |

So I am not alone :)
Can you do quick test with Firefox ( it gives me also warning message)
Please tell me your android version.

I also see this from an Android tablet when I use HTTPS, i.e. https://primes.utm.edu/ and its subpages. So the site seems to have an issue.
Note that the Top 5000 site also offers non-secure HTTP which of course can be used with no problems: http://primes.utm.edu/

Thanks about tip for non secure Top5000 page. This partially solves problem.
Would be useful to write Mr.Caldwell about issue?

Why do you think that the site has an issue?
The site has a valid certificate, and the encryption level is (Firefox, WIN10) "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, 256-Bit-Key, TLS 1.2". This is secure.
It seems to me that Andoid (client) isn't able to negotiate an appropiate security level in the server-client communication during instantiation of the connection. Maybe your Android version cannot handle TLS 1.2 (?)

Google also uses TLS 1.2 as Primegrid, and we dont have any problem with those sites.

Whatever the problem was, it appears to have been fixed now.
I speculate that it might have been the same problem described in this Stack Overflow answer.
