I have got a problem since Ubuntu 16.04 (still here in Ubuntu 18.04):

Some websites like https://github.com/ or https://bugs.launchpad.net/ aren't available in Chrome. I get an ERR_TIMED_OUT after some loading time. If I try loading the same website in firefox it takes some seconds but they are loaded correctly. If I try reloading the url several times in Chrome, at some point the website loads correctly. After a first full load I can browse through the website without any problems.

I tested it with LAN and WLAN, also in other networks and with a fresh chrome installation without add-ons. Problem still exists. If I am booting Windows (dual boot) the websites directly loads successful so the problem must be in the Ubuntu system.

if you are using docker on your system, then as here said remove useless docker networks and everything will be fine. it worked for me.

I was also stuck on browser and it was probably because I was running some docker containers, it caused this issue. I removed all the containers, images, docker network as well. Unfortunately, none of them worked for me. However, thanks to A J it was made clear for us. Go to this question and follow the instructions them step by step.

Try to stop all your running docker containers and prune your docker network. docker network prune may help you, but in my case it did not work as well. I deleted Chrome browser completely, but it also did not work as well. Some forms suggested to if you have same problem try to disable IPv6 in Network.

At first, I thought how that could be related, apparently, people in Chrome's forum says you need to that in order not to get stuck in browser, just giving you quick commands:

In order to disable IPv6, open with:

nano /etc/sysctl.conf

insert at the end what is given below:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

If IPv6 is still not disabled, then the problem is that sysctl.conf is still not activated.

To solve this, open a terminal with Ctrl + Alt + T and type the command:

sudo sysctl -p

You will see this in the terminal:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Run the following command:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

that will output:

1

which IPv6 has been successfully disabled.

  • No, none of them. given link is solution to the occurred problem but it is not duplicate questions, they are just related to this issue, in order to fix Chrome ERR_TIMED_OUT, you need to disable ipv6, and the answer is given in the link how to disable it. Whoever had this issue with Chrome says disable ipv6. – sebuhi May 19 '19 at 14:23

    Is that makes it clear? I completely explained the problem gave the solution as well. – sebuhi May 20 '19 at 04:00
  • Thanks! Seriously this worked for me in Ubuntu 18.04. I just disabled ipv6 and everything started working fine. – Manish Sep 22 '20 at 08:08
