Custom Domain Not Connecting to Base44 App
You've configured a custom domain for your Base44 app, but visiting the domain shows an error page, a default hosting page, or the connection times out entirely. The app continues to work on the default Base44 URL but not on your custom domain.
Custom domain configuration involves DNS settings that must be precisely correct, and errors in this process are common. The issue may be compounded by DNS propagation delays that make it hard to tell if your changes have taken effect.
Some users experience a partially working state: the domain loads but shows SSL certificate warnings, or it works without www but not with www (or vice versa).
Error Messages You Might See
Common Causes
- The CNAME or A record was not set correctly in the domain registrar's DNS settings
- DNS propagation has not completed yet (can take up to 48 hours)
- The custom domain was configured in Base44 but the DNS records point to the wrong target
- SSL certificate has not been provisioned yet for the custom domain
- The www and non-www versions are not both configured, causing one to fail
How to Fix It
Verify your DNS records using a tool like dnschecker.org to confirm the CNAME or A record is correctly set and has propagated. The target should match exactly what Base44's custom domain instructions specify.
If the DNS is correct but SSL shows a warning, the SSL certificate may still be provisioning. This can take up to an hour after DNS propagation completes.
For persistent custom domain issues, especially with subdomains, wildcard certificates, or complex DNS setups involving other services (like email on the same domain), a developer can help configure everything correctly.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.
Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
How long does it take for a custom domain to work with Base44?
DNS propagation can take up to 48 hours, and SSL certificate provisioning can take an additional hour after that. Wait at least 24 hours before troubleshooting further.
What DNS records do I need for a custom domain on Base44?
You typically need a CNAME record pointing to the Base44-provided target URL. Check the exact instructions in your Base44 app's domain settings for the correct target value.
