This module automates obtaining and renewing free SSL certificates from Let's Encrypt for your MikoPBX web interface. After setup, the HTTPS certificate is issued automatically and renewed on schedule — no manual steps required.
The module supports two verification methods:
The classic method — Let's Encrypt verifies domain ownership by making an HTTP request to your server on port 80. Simple setup: just enter your domain name and click save.
Requirements: port 80 accessible from the internet. The module opens it temporarily during verification and closes it immediately after.
Certificate issuance via your DNS provider's API. No need to open port 80 — works behind firewalls, NAT, and in private networks. Also supports wildcard certificates (*.domain.com).
Supported providers (20+): Cloudflare, Amazon Route53, GoDaddy, DigitalOcean, Hetzner, Yandex Cloud, OVH, Selectel, reg.ru, Beget, Namecheap, Azure DNS, Vultr, DuckDNS, Linode, INWX, DreamHost, deSEC, PowerDNS, ISPConfig, Google Cloud DNS, and any custom provider.
Setup: select DNS-01 in the verification method dropdown, choose your DNS provider, enter API credentials, and click save.

- For DNS-01 — select your DNS provider and enter API credentials
- Click save — the module requests a certificate from Let's Encrypt, progress is shown in real time
- Once issued, the certificate is automatically applied to the MikoPBX web interface
Auto-renewal runs on the 1st and 15th of each month. If the certificate is due for renewal, it will be updated automatically.
