Most webpages timing out

Seraphic8X · 2018-02-11 22:33:16

I'm quite new to arch, I'm having some trouble at the moment accessing certain webpages within all browsers (Firefox, Chromium, Opera). All the sites below work when I boot into Windows, but not in Arch. I do not have any issues at present with pacman, and when I ping the sites I get a response. I've checked quite a few other posts on this forum and others relating to this issue and cannot seem to find any way of fixing this.

So far I have tried:

Setting MTU to different settings (It's at 1500 but tried 1400, 1300, 1200, 1436 with no luck)
Disabling IPv6 in Firefox
Setting DNS servers to 8.8.8.8 and 8.8.4.4

Here are some examples of pages that do not work:

github.com
theguardian.com
askubuntu.com

Here are some examples of pages that do work:

google.com
archlinux.org
wikipedia.org
youtube.com

Is anyone able to give me a hand? Sorry, I've trawled through this forum and others and hit a brick wall.

EDIT: Also it just failed when retrieving a source on the command makepkg -s:

Do you want me to see if that works? That's not really the main problem, the main issue is that most web pages don't work. Once I get home from work I'll let you know.

seth · 2018-02-12 13:12:10

It'll pass you more information on *what* does not work.
Your list is too inconclusive, but there's at least github and askubuntu have DigiCert certificates.

Here is the result when I run curl:

(Though http/80 should be 301, but the test really doesn't mean anything)

Same on 443.

(...super stupid question...)

Is the date and time accurate in Arch Linux?

What version of Firefox are you using?

58.02, the issues occur in Chromium and Opera also.

It's okay! The date and time is correct.

Is sysctl net.ipv4.tcp_congestion_control set to bbr or cubic if bbr try setting it to cubic just to rule that out.

It's currently set to cubic, I'll try BBR and let you know!

net.ipv4.tcp_available_congestion_control = cubic reno

Seraphic8X · 2018-02-12 22:10:18

Nope, no luck there.

net.ipv4.tcp_available_congestion_control = bbr cubic reno

seth · 2018-02-13 10:19:37

bbr is actually the known troublemaker, so rather unset that again.

Can you reach those urls through a proxy? Do you maybe even use a proxy already?

Sorry about the delay, I've had a busy couple of days. I've just run curl through the proxy and it still didn't work

I don't use a proxy either. This is so frustrating because I've finally got into Arch after fiddling with it and giving up (I use a laptop with Optimus which is rather frustrating in itself!)

Here's the output:

I think it would be sane to post everythin related to your network setup: network type, network manager if any otherwise your manual configuration, your iptables or similar if any...

_PROXY is not listed in the curl man page as an environment option it uses. http_proxy is for http connections only but the protocol specified is https

Sorry there, typo. Either way it timed out.

seth · 2018-02-15 20:02:04

"ip route"?

Edit: adding to that, does it work on enp4s0, ie. the wired connection?

Yes it timed out but as

shows curl never attempted to connect to the proxy because that environment variables were incorrect. Nothing can be known if proxy use works on your system from the test as proxy use was never attempted.
Edit:
Example of a failed proxy attempt ( this is not meant to be copied )

I know it sounds odd but I don't have physical access to the router, I share a connection with my neighbour and use a wireless repeater. Keep in mind this does not affect windows or any other devices.

ip route:

default via 192.168.0.1 dev wlp5s0 proto dhcp metric 600 
192.168.0.0/24 dev wlp5s0 proto kernel scope link src 192.168.0.46 metric 600

Interesting.

tracepath github.com

Also clarify the typo thing, as loqs pointed out your first post is not from a proxy attempt, so you would have to have tried it with the correct environment variable afterwards.

What network type (e.g. vpn or simple xdsl connection...) and which network manager (NetworkManager, netctl, wpa_supplicant + dhcp...), but also:

cat /etc/resolv.conf
cat /etc/nsswitch.conf
dig google.com
dig github.com

Note: to use dig you have to install bind.
