Lets Encrypt SSL certificate will be available only for 90 days of period. To active again you need to go through issuance process again and installation process as well.<p>This is quite boring stuff, as you need to re-active and re-install SSL certificate on your server.<p>Better to buy SSL from other Trusted SSL certificate Authority which available for 1 to 3 year option.<p>One more disadvantage of Let&#x27;s Encrypt SSL Certificate is its only available for domain validated websites, so for business, e-commerce, banking and other platforms Lets encrypt is not available.
