[SOLVED] Steam cannot connect to internet(Error Code: -105)

upstartmass · 2025-06-28 01:32:38

Since yesterday, I have had an issue with Steam not properly connecting to the internet. However, my internet seems to be fine, as the I am currently accessing this website on the same computer and network. Also ping properly returns packets from terminal. Strangely, steam worked up until the point that I tried to setup a VPN yesterday. Because of that, I tried to reverse what ever I did yesterday, by completely deleting OpenVPN and ProtonVPN off of the system, but it didn't work. Next I tried to figure out if there was some kind of firewall issue (which hasn't been an issue before as this is my home network), but it doesn't say that my ports are blocked.

This is the current output of iptables (I am not really sure what this means).

 -> % sudo iptables -L -v                                        
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

When I run ip route I don't see any indication that I could still be connected to a VPN, as there is no tun0.

I also tried deleting the cache, reinstalling steam, installing the flatpak version, and none of them seem to work. Also strangely, I can see my friends list and see who is online, but cannot access anything else that requires internet, such as community posts and the store.

I believe it is likely related to the VPN installation, but I have exhausted my options as to trying to fix this myself and am not sure what else to try.

Please post the output of

Relevant steam ports: https://help.steampowered.com/en/faqs/v … -DA21-31EB

Did you end up installing nftables for your VPN shenanigans?
https://wiki.archlinux.org/title/Nftabl … e_firewall - this is active by default and blocks any inbound but ssh.
Also check nft ruleset and tables.

Edit: apparently steam yells that error on DNS issues

I actually did find that page with the relevant steam ports during my research, and tried to run some commands to ensure that they were forced open, but it didn't seem to have an effect. Potentially because I am not super familiar with networking.

And as far as I can remember, I don't think I downloaded nftables. I was mostly just working with OpenVPN and ProtonVPN.

Did you btw meatime reboot (as this will flush everything netfilter that wireguard/any vpn will have added)

I think that command is throwing an error:

Error: syntax error, unexpected string
list rulesetnft list ruleset
     ^^^^^^^^^^

Also, by reboot do you mean restarting the PC? Because I did try that a few times and it didn't work, so some of setting must have been changed somehow.

LOL, ctrl+p bounced.

nft list ruleset

but you /have/ https://archlinux.org/packages/extra/x86_64/nftables/ installed… so in doubt it's its firewall.
Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

lol, even funnier is the fact that I didn't even notice that it was the same command twice. It just looked like a typical command

But here is the output (the typo command didn't return anything):

The nftables.service isn't enabled - did you check drill and nslookup for steampowered.com ?

There's a disparity: some resolvconf got you the PNR 10.96.0.1 (which isn't your current segment) while the wifi connection is on 68.105.29.11 (your ISP)
Probably just fix the resolv.conf and re-establish the stub resolver symlink, https://wiki.archlinux.org/title/Systemd-resolved#DNS

Solved! I'm don't entirely understand what went wrong, but just in case someone in the future ever as the same problem, the following command fixed my issue with resolv.conf.

ln -sf ../run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

Thank you so much for your help.

When setting up the VPN something or someone replaced the resolv.conf symlink to the stub resolver w/ a real file with contents suitable for the VPN (but the DNS won't work w/o)
This condition never gets "automatically" undone.

In your defense: depending the resolved behavior on the filetype and a symlink to a different, incompatible config file sure sounded like a brilliant idea in someones head at some point, but in reality it's the dumb, convoluted, fragile shit that makes systemd so annoying.
