Today i received this email . kindly help me on this . Hello, Action may be required to prevent your Let's Encrypt certificate renewals from breaking. If you already received a similar e-mail, this one contains updated information. Your Let's Encrypt client used ACME TLS-SNI-01 domain validation to issue a certificate in the past 60 days. Below is a list of names and IP addresses validated (max of one per account): merchant.priceblaze.pk (38.108.7.164) on 2018-12-08 TLS-SNI-01 validation is reaching end-of-life. It will stop working temporarily on February 13th, 2019, and permanently on March 13th, 2019. Any certificates issued before then will continue to work for 90 days after their issuance date. You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire. Our staging environment already has TLS-SNI-01 disabled, so if you'd like to test whether your system will work after February 13, you can run against staging: [Staging Environment - Let's Encrypt](https://letsencrypt.org/docs/staging-environment/) If you're a Certbot user, you can find more information here: > [@How to stop using TLS-SNI-01 with Certbot](https://community.letsencrypt.org/t/how-to-stop-using-tls-sni-01-with-certbot/83210): > > L… Our forum has many threads on this topic. Please search to see if your question has been answered, then open a new thread if it has not: [https://community.letsencrypt.org/](https://community.letsencrypt.org/) For more information about the TLS-SNI-01 end-of-life please see our API announcement: > [@March 13, 2019: End-of-Life for All TLS-SNI-01 Validation Support](https://community.letsencrypt.org/t/february-13-2019-end-of-life-for-all-tls-sni-01-validation-support/74209): > > L… Thank you, Let's Encrypt Staff ---

Hi @fayaz - update your certbot, so you use a version \>= 28.0 - create a new test certificate with `--dry-run` as option If that works, it should work directly. > [@fayaz](#): > > merchant.priceblaze.pk (38.108.7.164) on 2018-12-08 Your domain has blocked mixed content ( [https://check-your-website.server-daten.de/?q=merchant.priceblaze.pk](https://check-your-website.server-daten.de/?q=merchant.priceblaze.pk) ), so JavaScript code is missing and the site may not work as expected. ```nohighlight script http://code.jquery.com/jquery-2.0.0b1.js 1 mixed script http://code.jquery.com/jquery-migrate-1.0.0.js 1 mixed ``` It's curious, FireFox blocks this complete, so no warning is visible. ---

Yes, since you already have `certbot`, both may produce the same result: `sudo yum install python2-certbot-apache` `sudo yum update python2-certbot-apache` [if not, then do both] ---

It seems that when you last renewed you used `--standalone` That is not recommended; as it requires to stop your web server in order to spin up a new temporary web server to serve the authentication challenge requests. **Unless you are ok with stopping the web server temporarily?** [during the test only - then you can start it again] Otherwise, we would have to try using --webroot instead. But that would require determining the webroots for each domain. [that could take some time] ---
