Cloudflare try constantly to certificate a site that I removed

Website, Application, Performance DNS & Network
1

What is the name of the domain?

What is the error number?

I remove my site from cloudflare, but cloudflare continue to try to certificate the ssl of my site (I don’t need it because I have a certbot with letsencrypt) and I’m receiving this error: 2024/08/22 09:26:41 [info] 140#140: *257 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.70.203.138, server: 0.0.0.0:443 2024/08/22 09:26:41 [info] 140#140: *259 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.69.105.141, server: 0.0.0.0:443 2024/08/22 09:26:41 [info] 140#140: *262 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.69.175.141, server: 0.0.0.0:443 2024/08/22 09:26:41 [info] 140#140: *263 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 162.158.134.125, server: 0.0.0.0:443 2024/08/22 09:26:41 [info] 140#140: *264 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.68.191.150, server: 0.0.0.0:443 2024/08/22 09:26:41 [info] 140#140: *265 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.68.114.132, server: 0.0.0.0:443 2024/08/22 09:26:41 [info] 140#140: *267 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.69.168.205, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 140#140: *268 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 162.158.87.209, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 141#141: *270 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.68.130.138, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 140#140: *269 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.71.124.59, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 140#140: *272 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.71.167.89, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 140#140: *271 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.69.89.137, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 140#140: *273 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.71.89.135, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 142#142: *276 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.70.82.81, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 141#141: *275 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 162.158.98.139, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 140#140: *274 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 162.158.231.138, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 141#141: *277 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.70.180.144, server: 0.0.0.0:443 2024/08/22 09:26:42 [info] 141#141: *278 SSL_do_handshake() failed (SSL: error:0A000412:SSL routines::sslv3 alert bad certificate:SSL alert number 42) while SSL handshaking, client: 172.68.162.141, server: 0.0.0.0:443

What steps have you taken to resolve the issue?

Everythin, I don’t know why after remove the site from cloudflare cloudflare continue to check the ssl

What feature, service or problem is this related to?

I don’t know

Hi there,

That’s an SSL_do_handshake, not a certification.
It means a system somewhere, behind Cloudflare, is trying to establish a TLS connection to your hostname and failing.

Take care.
