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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Thanks for the response. I installed it via my host’s control panel this time last year. There’s a message under the Let’s Encrypt panel saying they will attempt to renew it automatically. But there’s no obvious way to renew it manually.
You might want to signup for a free cert monitoring system.
That can email you when your cert is getting close to expiry.
That way you can get to them BEFORE it expires.
Since it seems they are not staying on top of that aspect.
Thanks for the advice. I’ve now done this. It looks like Let’s Encrypt certificates only last for 90 days. Do you know if this is correct? I thought they were for a year.
