Problem connecting to a website

General Questions
#1

I need to access the OpenCV documentation, for some reason I can’t get onto the documentation website at docs.opencv.org. Well, I can… on my phone, but only if it’s connected to 3G. If it (or any device in my house) is connected via my home network, I can’t get to the site.

Here’s the results of a tracert


Tracing route to docs.opencv.org [81.176.228.4]

Note that 3 always times out, even if I’m doing a tracert to a site I know I can get to like Google or my DNS. I’m pretty sure that step is my modem since we have two routers (one is for a security system and the other connects through it via a DMZ). This is the only site I can’t connect to that I know of.

Is this on my end, or is there some problem with my ISP? I checked normal stuff like a wonky hosts file, but since the tracert escapes my local network and gets halfway there I wonder if it’s something that’s out of my hands.

Oh, and I tried all the standard “reboot your router/modem/computer” stuff.

#3

The URL works here on Firefox for Windows. I’m in Virginia.

The Tracert works too, all steps look normal. Hops 15-17 out of 18 are .ru addresses though.

#4

just throwing this in on the off chance, i had a similar thing, turned out my router had some sort of firewall or block list… changed the router and it was fine. Might be worth looking at.

#5

Try going through a proxy or this other one.

See if the routing issue clears up in a few days by itself. If not, talk to your ISP.

#6

Yup, I can get in through a proxy, thanks. It was almost certainly my ISP because I had my mom try it at her work, which has the same ISP, and she couldn’t connect either.

#7

Yeah, that’s what usually causes these issues. The internet is a pretty flakey thing and intermediary connections go down randomly all the time. They’ll usually resolve themselves soon :slight_smile:

In the future you can look for “down for everyone or just me” websites, or try on your phone again. You can also add “nyud.net” to the end of any domain name, keeping the rest of the URL the same, and a global network of proxies will attempt to fetch it for you, for free, courtesy of CoralCDN.
