Suddenly today—without explanation—I cannot access my web server from my local network. My router is an Actiontec MI424WR MI424WR (GigE for Verizon FiOS). I have verified that no browser running on any Windows PC can access the site within my LAN.
I have also verified that the site is up. Strangely, it seems to work within my network on Android devices. I have not yet tried iOS or Mac OS X. Just Windows and Ubuntu systems running a slew of browsers. They all give me a DNS error.
I have checked my “Windows Firewall” settings and see no recent changes. Same with my router. My network is performing normally other than this anomaly, which suddenly started happening today.
I host the website myself, but I tried going to my registrar (1&1 Internet) to see if something happened there. I get the same DNS error as with my website, although “IsItDownRightNow” insists that their services—as well as my web server—are up and running.
If I type the internal IP of my server into any browser the site works. If I type the external IP I get the DNS error.
Any ideas? My server is still up and running, so this isn’t super critical. I would like to be able to access my own server, however.
