Wix automatically provisions and renews an SSL certificate for every site, including custom domains connected through its dashboard, with no manual certificate installation required — there's no CSR to generate or file to upload.
What to actually check
Go to Settings → Domains, click your connected domain, and confirm the SSL status shows as active. If you recently connected a custom domain, allow up to 24-48 hours for DNS propagation and automatic certificate issuance to complete.
If HTTPS isn't showing as active
The most common cause is DNS records that haven't fully propagated, or a domain still pointed at its previous host's nameservers rather than Wix's. Double-check the domain connection status before assuming it's a certificate-specific problem.
What to do if your custom domain's SSL takes longer than expected
If SSL hasn't activated within 48 hours of connecting a domain, the most common cause is a DNS record that's slightly incorrect or still pointed at a previous host — double-check the exact records against Wix's current documented values, and use a DNS propagation checker to confirm the change has actually reached major resolvers worldwide.
Why Wix's managed approach removes an entire category of troubleshooting
Because Wix controls both the hosting and certificate issuance end to end, you never need to generate a CSR, install a certificate manually, or manage renewal — the entire category of installation and chain-completeness issues covered elsewhere on this site simply doesn't apply to a standard Wix-hosted site.
What to expect if you're migrating an existing domain onto Wix
Moving a domain that previously had HTTPS elsewhere onto Wix means starting fresh with Wix's own certificate provisioning rather than transferring anything from the old setup — plan for a brief window where DNS is transitioning and the new certificate is being issued, similar to connecting any new custom domain.
What happens to old http:// links pointing at your Wix site
Wix's platform-level HTTPS enforcement automatically redirects any incoming http:// request to the https:// equivalent, meaning old bookmarks, backlinks, and search results referencing the plain HTTP version continue working correctly without any additional configuration on your part.
Why Wix doesn't offer a manual certificate upload option
Wix's fully managed hosting model doesn't expose certificate management to site owners at all, by design — this trades away the flexibility a self-managed server would offer (choosing a specific CA, a particular validation tier) in exchange for zero ongoing maintenance burden, a reasonable trade for the platform's target audience of non-technical site owners.
How to verify your site's certificate details if you want to check manually
Even without direct management access, you can inspect the actual certificate Wix has issued for your domain the same way you'd check any site — clicking the padlock in your browser shows the issuer, validity dates, and coverage, confirming everything is correctly in place independent of Wix's own dashboard.
A final practical note for anyone comparing Wix against a self-managed alternative
The trade-off Wix represents is worth naming plainly: you give up granular control over certificate type and validation tier in exchange for genuinely zero ongoing maintenance — for the overwhelming majority of Wix's target audience, that trade is clearly worth it, since DV coverage through a managed platform is functionally identical in encryption strength to anything you'd configure manually.
What a small business owner without technical staff should actually do here
For the typical Wix user without in-house technical staff, the practical action item is simply confirming the SSL status shows active under Settings → Domains once, after connecting any custom domain — beyond that single check, there's genuinely nothing further to configure or maintain.
How this compares to the effort required on a self-managed WordPress site
Where a self-managed WordPress migration involves certificate installation, database updates, and redirect configuration as covered in our dedicated WordPress guide, Wix collapses that entire multi-step process into automatic platform behavior requiring no comparable manual effort at all.
