People can’t open website on older mobile phone devices, they are getting notification that “website is not secure”, but website have valid SSL certificate issued automatically by Let’s encrypt, and lockpad working on new devices and windows computer. Lockpad not working for example on old Samsung phone A8.
I am informed by Domain provider that only you can fix it. Need to add TLS ver.1.2, and maybe to disable ver.1? What you can do?
Hi @sasamilivojev , and welcome to the LE community forum
Please fill out this form (you have already supplied some of the information, thank you):
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know):
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
Thank you, but I don’t understand this. I just can see that my website not working on older mobile phones, “not secure”. I am using Plesk. What I can do? How to add tls ver.1.3 ? Or Lets Encrypt will fix this?
Help please

Thank You, I think that you are right. One is expired ZeRo SSL which I added before, but after - domain provider installed Lets encrypt for me, and now I am getting new certificate automatically after 90 days.
So what I can do? To delete all old certificates in Plesk?
Lockpad working on Windows computer and Iphone, not wotking on old Samsung A8 for example.
I am new here, and I don’t understand tls, expiriance: Zero. I only can see that my website not working on old mobile phones and looking for help how to fix. Technical support of domain and hosting provider don’t care for my problem
Thank you. So what I can do now? In Plesk to remove expired certificates and use only Automatic Let’s encrypt? Than website will work on older mobile phones?
Provider don’t care. They told me to ask for help Internet Engineering Task Force (IETF), but IETF replied to me to ask for help here at community.letsencrypt.org
