12. If the DNS records for "a.b.c.d" resolve to the IP address of your computer, then your DNS settings are correct. If the DNS records for "a.b.c.d" don't resolve, then your DNS settings probably need to be updated.

4. Check your firewall settings

1. In your web browser, type "firewall status" into the address bar.
2. When the firewall status page appears, scroll down to the "FirewallRules" section.
3. In the "FirewallRules" section, locate the rule that is causing the error.
4. If the rule is a standard Windows firewall rule, double-click on it to open it.
5. If the rule is a custom rule, you will need to open the rule in a text editor such as Notepad.
6. In the "FirewallRules" section, find the "Host" section.
7. In the "Host" section, find the "NotAvailable" line.
8. Change the "NotAvailable" line to "Available."
9. Save the rule.
10. Test the firewall status by typing "firewall status" into the address bar.

5. Check if the host is online

1. In a command prompt, type "ping 127.0.0.1" and press Enter. If the computer can reach the host at 127.0.0.1, then the host is online.
2. In a command prompt, type "netstat -ano" and press Enter. If the host is online, the command output should include the following line: TCP 0 0 localhost:8080 0.0.0.0:* LISTEN
3. In a command prompt, type "nc 127.0.0.1 8080" and press Enter. If the host is online, the command output should include the following line: localhost:8080 > CONNECTED (8)
4. If the host is not online, the command output should include the following line: localhost:8080 > CONNECTED (8) and the following four lines: UDP 0 0 127.0.0.1:8080 0.0.0.0:* TCP 0 0 localhost:8080 0.0.0.0:* TCP 0 0 localhost:80 0.0.0.0:* TCP 0 0 localhost:443 0.0.0.0:*

6. Try connecting to the host using a different method

1. Verify that the host is actually unavailable.
2. Verify that the network connection is active and working.
3. Verify that the hostname or IP address is correct.
4. Verify that the port is open and accessible.
