Custom Domains

Connect your own domain to give your INSTROC app a professional web address.

Overview

By default, your app is available at yourproject.instroc.app. With a custom domain, you can use your own address like www.yoursite.com.

Requirements

To use a custom domain, you need:

• A domain you own (from any registrar)
• Access to your domain's DNS settings
• INSTROC Pro plan or higher

Connecting a Domain

Step 1: Add Your Domain

1. Open your project in the editor
2. Click Publish → Settings
3. Click Add Custom Domain
4. Enter your domain (e.g., www.yoursite.com)

Step 2: Configure DNS

INSTROC provides DNS records to add at your registrar:

For subdomains (www, app, etc.):

Type	Name	Value
CNAME	www	customers.instroc.app

For apex domains (example.com):

Type	Name	Value
A	@	66.51.124.51

Step 3: Verify

1. Add the DNS records at your registrar
2. Return to INSTROC and click Verify
3. DNS propagation takes 5 minutes to 48 hours
4. SSL certificate is automatically provisioned

Step 4: Deploy

Once verified, your domain is ready:

1. Click Deploy
2. Your app is live at your custom domain!

Domain Types

Apex Domain

The root domain without any subdomain:

• example.com
• mysite.io

Requires an A record pointing to our IP address.

Subdomain

A prefix before your domain:

• www.example.com
• app.example.com
• blog.example.com

Uses a CNAME record pointing to customers.instroc.app.

WWW vs Non-WWW

We recommend using www.yoursite.com because:

• Better CDN compatibility
• Easier DNS management
• Industry standard for websites

INSTROC can redirect non-www to www (or vice versa) automatically.

• Active - HTTPS is working
• Error - Check DNS configuration

Troubleshooting

Domain Not Verifying

DNS not propagated

• Wait up to 48 hours
• Use dnschecker.org to check status

Wrong records

• Verify record type (A vs CNAME)
• Check for typos in values
• Remove conflicting records

Proxy enabled

• If using Cloudflare, set to "DNS only" initially
• After verification, you can enable the proxy

SSL Certificate Errors

Certificate pending

• Wait 10-30 minutes after DNS verification
• Clear browser cache

Mixed content

• Update hardcoded http:// URLs to https://
• Check for external resources loaded over HTTP

Site Not Loading

DNS cache

• Try incognito mode
• Wait for local DNS cache to expire

Wrong domain in settings

• Primary domain used for SEO
• Additional domains redirect to primary

Best Practices

Use HTTPS

Always use HTTPS for security and SEO. INSTROC enforces this automatically.

Set Up Redirects

Configure www/non-www redirects for consistency.

Monitor Expiration

Ensure your domain registration doesn't expire—set up auto-renewal.

Backup DNS

Document your DNS settings before making changes.
