Cannot access our own website internally

Hi there,

I have recently upgraded our internal network to a brand new Windows server 2019 with all the latest updates and a fresh Active Directory.

Since doing that none of the computers on the internal network can access our company webiste www.alcom-it.co.uk


Have tested in Edge, Chrome and Firefox but all 3 just timeout and give this error...



This site can’t be reached



www.alcom-it.co.uk took too long to respond.
Try:

  • Checking the connection

  • Checking the proxy and the firewall

  • Running Windows Network Diagnostics

ERR_CONNECTION_TIMED_OUT


Tearing my hair out now so any suggestions would be most welcome.

Thanks,

Abe

@Abe-9530 There are many reasons for this error, need more information for troubleshooting, first you can try to ping your website to see if it succeeds, and check if there are related error messages in the event viewer. and can you share the settings of website in your iis?

We don't have an IIS server running. Our website is hosted externally.

I can access the website when I am out of the office but when I am in the office the website does not work.

I have run a ping test and these are the results

Hello @Abe-9530,

I felt proxy-embarrassment when reading this.

nslookup suggests that the public IP addresses of www.alcom-it.co.uk are: 2606:4700:3035::ac43:b9f4, 2606:4700:3030::6815:206d, 104.21.32.109, 172.67.185.244.

192.168.100.254 is a private network IP address. There is obviously some misconfiguration of the company internal DNS for the name www.alcom-it.co.uk.

Gary
