ThaiDataHosting SSL 2026

Free SSL on every ThaiDataHosting plan
The first thing most ThaiDataHosting users ask is whether SSL costs extra — it doesn't. Every plan, from Cloud Linux Hosting Fusion for small sites to the VIP tier for high-traffic sites, plus WordPress Hosting and Cloud VPS SSD, ships with a free SSL certificate built in. The issued certificate is a DV (Domain Validated) Let's Encrypt cert, trusted by every major browser exactly like a paid certificate.
Because ThaiDataHosting runs a Bangkok node on All-Flash NVMe SSD hardware, the TLS handshake between Thai visitors and the server completes quickly with low latency — so encryption doesn't add the lag you'd get from an overseas server. SSL here is about security and trust without a speed penalty.

Visit ThaiDataHosting →Enabling SSL in DirectAdmin
ThaiDataHosting uses the DirectAdmin control panel, so the menu layout differs slightly from generic tutorials. Log in to DirectAdmin, open Account Manager → SSL Certificates, choose "Free & automatic certificate from Let's Encrypt," tick the domain and any subdomains (such as www) you want covered, then click Save and wait one to two minutes for issuance.
On plans where SSL is provisioned automatically when a domain is added, the certificate may already be live without doing those steps — check the SSL Certificates page for a "valid" status and simply re-issue if it hasn't appeared yet.
How SSL/TLS actually works
SSL/TLS encrypts the connection between a visitor's browser and the server, so passwords, card numbers, and personal data crossing the network can't be intercepted. People still call it "SSL," but ThaiDataHosting servers use modern TLS (1.2 and 1.3), which is faster and more secure than the old protocol.
When it's active, the URL switches from http:// to https:// and a padlock appears in the address bar. TLS 1.3 also reduces the number of handshake round-trips, so connections establish faster than on older versions — a small but real win for Core Web Vitals.
DV vs OV vs EV: which do you need?
The free SSL bundled with ThaiDataHosting is DV, which covers the needs of most sites. DV only confirms you own the domain, issues instantly, and is plenty for blogs, company sites, and typical online stores. OV (Organization Validated) verifies a real organization and must be purchased separately, while EV (Extended Validation) is the strictest tier, now mostly used by financial institutions.
The practical advice: start with the free DV certificate. If you later genuinely need OV or EV, contact the ThaiDataHosting team to arrange a paid certificate at that point rather than over-buying up front.
Forcing HTTPS on every page
Once SSL is active, force every visitor onto https:// so no one lands on an unencrypted page. Some DirectAdmin versions include a "Force SSL/HTTPS redirect" toggle in the domain settings — one switch and you're done. Otherwise, add a redirect rule to the .htaccess file in public_html.
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
On WordPress, the Really Simple SSL plugin handles redirects and mixed-content rewriting automatically — just avoid stacking a plugin redirect on top of an .htaccess rule, which can cause a loop.
Automatic renewal
Let's Encrypt certificates last 90 days, shorter than commercial 1-2 year certs, but ThaiDataHosting's DirectAdmin is set to renew them before expiry automatically — you never renew by hand. Check the SSL Certificates page if you want to confirm the status. Renewal usually only fails when the domain points to the wrong IP, a CAA record blocks issuance, or a deleted subdomain is still listed; fix that and re-issue, or open a ticket if it persists.
Wildcard SSL for subdomains
If your site uses several subdomains — blog.yourdomain.com, shop.yourdomain.com, and so on — you can request a single wildcard certificate covering *.yourdomain.com instead of issuing one per subdomain. Let's Encrypt verifies ownership through a DNS challenge, and the ThaiDataHosting team can help configure the required DNS records if you're not comfortable doing it yourself.
Common SSL troubleshooting
The most frequent issue is a page still showing "Not Secure" after installation — almost always Mixed Content, where images or scripts still load over http://. Fix it with Really Simple SSL or by search-replacing links in the database. ERR_SSL_PROTOCOL_ERROR usually clears after wiping browser cache and cookies; a "Certificate Not Trusted" warning points to a broken chain that the team can re-issue via DirectAdmin; and "Too Many Redirects" means HTTPS forcing is set in two places at once — keep it in only one. If SSL doesn't cover a subdomain, add that subdomain when issuing the certificate or switch to a wildcard.
