My users get "net::err_name_not_resolved"

Question

I did get messages from android phone users that my website is not loading.

When an android phone clicks on a link to go to my website it gets the error: net::err_name_not_resolved

On computers and iPhones, I don't get the error. When the android user copies the link and pastes it into the browser the website loads correctly.

Link to my website: https://www.losangelestorrevieja.com

I have custom resource records from google:

• Name: *
• type:CNAME
• Info:www.losangelestorrevieja.com.

.

• Name: wwww
• type:CNAME
• Info:enzotrompeneers.github.io.

if I nslookup www.losangelestorrevieja.com I don't receive an IP address

Solution 1

I believe it was DNS propagation issue and it's now resolving, it may take up to 48 hours for some nameservers to catch new changes

Solution 2

I think it's already solved, i tried nslookup'ing and acessing with my Android phone, both worked.

Depending on DNS Server, it may take some time to update. Maybe this was your problem, the reflection isn't instantaneous.

Solution 3

The www domain itself resolves: www.losangelestorrevieja.com.

But the SSL certificate does not cover: losangelestorrevieja.com.

SSL test says:

Certificate not valid for domain name

Requesting from Google DNS servers 8.8.8.8 or 8.8.4.4 might have the DNS updates from Cloud DNS eg. ns-cloud-c1.googledomains.com the soonest. It generally can take up to 24 hours until it can be resolved by any DNS server (even if in most cases, this happens rather instantly). Even when using a DSL router, one can change the default (ISP provider assigned) DNS server to any other DNS server (in case it not updates from Cloud DNS too soon).
