Question:

Greetings,

I own a straightforward website hosted on Google Sites, which is associated with my custom domain through Google Domains. In an attempt to secure my site, I registered it with CloudFlare, necessitating a change in DNS settings. However, this introduced a proxy that rendered my site inaccessible. Unable to resolve the issue, I withdrew my site from CloudFlare, but now I am unable to restore its online presence.

I have reverted the DNS records to their presumed original state:

• Hostname: www
• Type: CNAME
• TTL: 30 seconds
• Data: ghs.googlehosted.com.

Additionally,

• Hostname: @
• Type: A
• TTL: 30 seconds
• Data: 216.239.32.21, 216.239.34.21, 216.239.36.21, 216.239.38.21

I have also switched back to Google’s default nameservers.

Despite these efforts, my URL yields the error: ‘This site can’t be reached. ERR_CONNECTION_CLOSED.’

I am at a loss for what has transpired and have exhausted all relevant Google FAQs to no avail.

Would you be so kind as to assist me in reviving my website?

Thank

you in advance for your expertise.”

Answer:

Dear Website Owner,

It appears you’re facing a common yet complex issue that can arise when modifying DNS records. The transition to and from CloudFlare’s network involves changes that can affect your website’s accessibility. Let’s dissect the problem and explore potential solutions.

Firstly, reverting to the original DNS settings was a logical step. However, DNS propagation can take up to 48 hours. During this period, your website may be intermittently accessible or completely unreachable. Here’s what you can do:

: Use online tools to verify if your DNS changes have propagated across the internet. If they haven’t, you may need to wait longer.

2.

DNS Configuration Verification

:

–

CNAME Record

: Ensure the `www` hostname CNAME record points to `ghs.googlehosted.com`. This is crucial for Google Sites.

–

A Records

: The IP addresses listed should be verified against Google’s documentation for accuracy.

3.

SSL/TLS Certificate

: CloudFlare provides an SSL certificate for secure connections. Removing your site from CloudFlare might have affected this. Check if your website’s SSL certificate is valid and properly configured.

4.

Firewall and Security Settings

: Sometimes, security settings can inadvertently block traffic to your site. Verify that your firewall rules are not preventing access.

5.

Contact Support

: If the issue persists, reach out to both Google Domains and CloudFlare support. They can provide insights specific to your situation.

6.

Browser Cache

: Clear your browser cache or try accessing the site from a different browser or device to rule out local caching issues.

7.

Google Nameservers

: Confirm that you’re using the correct nameservers provided by Google. Incorrect nameservers can lead to connection errors.

In conclusion, patience is key during DNS transitions. If after thorough checks your site remains inaccessible, professional assistance from the services you’re using may be necessary. Rest assured, with careful troubleshooting, your website should be back online soon.
