[SOLVED] can't connect to most websites

eatmydiarrhea · 2022-09-25 02:39:02

Fresh install of arch and I'm on i3 then installed firefox. I also installed NetworkManager, ModemManager and enabled/started the services successfully. I can connect to some websites (flawlessly): google,youtube,gmail,archlinux,& more. The error I get on other websites, say reddit, is just the generic can't connect error:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.reddit.com.

If you entered the right address, you can:

    Try again later
    Check your network connection
    Check that Firefox has permission to access the web (you might be connected but behind a firewall)

but when I ping reddit.com in terminal, it's successful and has a response time of ~15ms. I initially thought it was an issue with SSL but decided against it because I setup my date and time when installing, and when I get SSL issues it usually results in some websites loading improperly, and a variety of errors instead of the generic one. Hope somebody can help, I need this to work so I can debug issues by myself, thanks

Do you have an IPv4 address? I've seen this happen on IPv6 only systems, they can't access sites that don't have IPv6.

yes, unfortunately you are correct, I have an IPv6 address only. Is there anything I can do?

btw: I didn't run into this issue on ubuntu, win7 or win10

Remove the "unsolved" nonsense from the subject, that's assumed.

Is there anything I can do?

Identify the problem

I can connect to some websites … I ping reddit.com in terminal, it's successful

and fix your network configuration.

Let's start w/ some usable data:

ip a
ip r
resolvectl status
dig reddit.com
dig @8.8.8.8 reddit.com
find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
sudo journalctl -b | curl -F 'file=@-' 0x0.st # if this doesn't work
sudo journalctl -b > /tmp/journal.txt # and upload that file somewhere somehow

looks like you are having this problem.

Though www.reddit.com redirects to reddit.map.fastly.net and unlike reddit.com doesn't seem to have an AAAA record, so he might have been testing different domains, there're MANY reasons why the OP could end up w/o an IPv4 lease/route - protocol issues w/ a specific server are only one of them - and not the common one (esp. since he had no issues w/ ubuntu)

thanks, fixed after install dhcpcd and dhclient, then services dhcpcd.service, dhcpcd@lo.service, dhcpcd@enp3s0.service, dhclient@enp3s0.service, dhclient@l0.service. Don't know if I set it up right but im still taking this W cause it works <3

So now next to NM you've enabled a bunch of dhcpcd and dhclient services - if anything you've made the situation worse.
Post the outputs I asked for in #4

dhclient@enp3s0.service                  | multi-user.target.wants
dhclient@lo.service                      | multi-user.target.wants
dhcpcd@enp3s0.service                    | multi-user.target.wants
dhcpcd@lo.service                        | multi-user.target.wants
dhcpcd.service                           | multi-user.target.wants
NetworkManager.service                   | multi-user.target.wants
NetworkManager-wait-online.service       | network-online.target.wants

You have now 3½ services competing for the same NIC configuration,

If you want to use dhcpcd OR dhclient as backend of networkmanager, you'd have to https://wiki.archlinux.org/title/Networ … HCP_client and under no circumstances enable them by themselves.

Edit: there's however no reply for

Sep 24 22:17:49 Boss NetworkManager[503]: <info>  [1664072269.3023] dhcp4 (enp5s0): activation: beginning transaction (timeout in 45 seconds)

so you might indeed run into a protocol issue w/ NMs internal dhcp implementation and substituting that therefore a usable workaround for your problem.
