Datanza.com is not redirecting to OCI load balancer IP 130.162.34.183 rather redirecting to www1.datanza.com and 4020 number only displayed on screen

I only get a 521 and that’s because the mentioned IP address is not responding.

Community Tip - Fixing Error 521: Web server is down has more on that.

There’s also no www1 record, so you’ll most likely have some DNS resolution issue and use some previous values. Check your local DNS resolver.
