If you can successfully ping the IP address of your Jira server but not the domain name (https://test.hello.com
), this suggests a DNS (Domain Name System) resolution issue. The DNS is responsible for translating domain names into IP addresses. Here are some steps to address this problem:
- Flush DNS Cache:
- On Windows, open Command Prompt and run
ipconfig /flushdns
. - On macOS, open Terminal and run
sudo killall -HUP mDNSResponder
. - On Linux, the command depends on your distribution and the DNS service you are using, but a common command is
sudo systemd-resolve --flush-caches
.
- On Windows, open Command Prompt and run
- Check DNS Settings:
- Ensure that your computer’s DNS settings are correct. You might want to try using a public DNS service like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).
- Verify Domain Name:
- Double-check the domain name for typos.
- If you have access to your domain’s DNS records, verify that the A record for
jira.hello.com
is pointing to the correct IP address.
- Hosts File:
- Check your computer’s hosts file to see if there’s an entry for
test.hello.com
. Sometimes, this file may contain static entries that can override DNS settings. - On Windows, the hosts file is usually located at
C:\Windows\System32\drivers\etc\hosts
. - On macOS and Linux, it’s typically at
/etc/hosts
.
- Check your computer’s hosts file to see if there’s an entry for
- Network Configuration:
- If you’re on a corporate network, there might be network policies or firewall settings that affect DNS resolution. Check with your network administrator if this might be the case.
- Contact ISP or Network Administrator:
- If you’re unable to resolve the DNS issue, it might be worth contacting your Internet Service Provider (ISP) or network administrator for assistance.
- Testing on a Different Network:
- If possible, try accessing the Jira domain from a different network (like a mobile data connection) to see if the issue is network-specific.
- Check with Jira Server Admin:
- If you’re not the Jira server administrator, get in touch with them to ensure there are no issues with the server’s DNS configuration or domain name registration.
