My WAN IP changed recently. I know not when. I updated my DNS service to the new IP several hours ago, but my web site is still timing out, as is trying to reach it via my router's WAN IP. Update never took more than a few minutes to propagate before. Could something have changed in apache2 that didn't take effect right away? Last zypper up was 03 November @05:09. Apache2 log entries stopped 6 November @00:14. Last apache2 entry I see in zypper's history was on 2 November @23:33. # systemctl status apache2 ● apache2.service - The Apache Webserver Loaded: loaded (/usr/lib/systemd/system/apache2.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2020-11-03 03:35:01 EST; 4 days ago Main PID: 1098 (httpd-prefork) Status: "Total requests: 0; Current requests/sec: 0; Current traffic: 0 B/sec" Tasks: 11 I called my ISP, who claimed no blame, not blocking port 80. I reset my router, and see nothing awry in its settings, or an available update. Where should I look to troubleshoot this? -- Evolution as taught in public schools, like religion, is based on faith, not on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!

There have been recent updates to apache. You have to connect to internet a laptop using some other Internet provider and check if you get the correct IP to the host command, and whether ping reaches the machine. You know there are ping programs that can use tcp port 80. And then, try to reach your web server both by IP and by name. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

On my LAN inside the router it's reachable both by IP and by hostname. Yet outside nada. Router seems to be confused. https://whatismyipaddress.com/ reports WAN IP is 24.50.25.152, but I don't see that IP anywhere in my router's admin/setup, where it seems to be 100.73.40.34. # dig +short myip.opendns.com @resolver1.opendns.com 24.50.25.152 # curl ifconfig.me 24.50.25.152 curl http://whatismyip.akamai.com 24.50.25.152 Called my ISP, which said my account wasn't configured for a bridge between cable modem and separate router. It assumed I had combo modem/router so had to change some "things" to implement bridge. I spent a lot of time waiting for ISP to monkey around, and it came back again with 100.73.40.34. So I tried setting my router to static 100.73.40.34, but it didn't help. Cycling power on router multiple times didn't helped either. https://www.whatsmydns.net/#A/fm.no-ip.com shows propagation of 100.73.40.34 now. speedtest-cli still reports 24.50.25.152 https://downforeveryoneorjustme.com/fm.no-ip.com just reported still down, but I just got Firefox to load http://fm.no-ip.com/Auth/dpi-screen-window.html and Chromium to load http://fm.no-ip.com/, yet, speedtest-cli still reports 24.50.25.152. After a while I'll have to try switching router back to DHCP and see whether it holds or again breaks. :P -- Evolution as taught in public schools, like religion, is based on faith, not on science.

Smartphone tethering? internet cafe? Tablet or smartphone connected to phone?

speedtest-cli still reports 24.50.25.152

https://downforeveryoneorjustme.com/fm.no-ip.com just reported still down, but I just got Firefox to load http://fm.no-ip.com/Auth/dpi-screen-window.html and Chromium to load http://fm.no-ip.com/, yet, speedtest-cli still reports 24.50.25.152.

After a while I'll have to try switching router back to DHCP and see whether it holds or again breaks. :P
