Unable to access Steam store error 118 and 105

[Frank Spasic]

I've noticed today that I've been completely unable to access the steam store on my home network. I know there are a million other threads related to these errors.

My case is that, as stated, I'm unable to access it on MY network. Like every device on my network cannot reach the page via any avenue as though it is blocked.

I can't reach through IOS app on the iphone, I can't access through safari browser, three windows 10 computers via LAN or wifi.

- I've disabled the firewall on my modem

- I've connected to cellular towers instead and I WAS able to connect so I doubt it's my account, also I'm not able to access it through browsers not logged in to any account.

- I've already tried switching DNS as I was using a pi hole, and I thought that was it. I now have plenty of ads but no steam store

- I've checked my modem and it is not blocking any ip's (I'm a network engineer by trade so I've checked most things there)

Any suggestions or links to solved similar issues would be appreciated. I've seen several threads from other users with the same errors, but not found any related to their whole network. It's almost as if my ip address itself is blocked, and I have not tried routing through a VPN but that doesn't actually solve my problem. That would just be a temporary workaround, and I feel it would be pointless to spend time on that avenue. I would rather diagnose the root problem.

try reboot router , either you have static entry or ISP change something, and could be seen as users own faulth, router that adapt to change is the right way in configuration, but its just a best guess, or what about ISP did work and you did not know about it, its vital to know own ISP work notification , but sure error can still happend. and lines are down. until fixed.

copy from other 118 try to look into 105 to see if this give a clue.

i have tryed to look into this, found some odd solutions , reboot Router, wait 3 minutes then all work again, if this is the case then, either router is static configurated and dont adapt then change or ISP change something and can cause this. ( and you might want to reset own configuretion if isp has change something and you still use static entry, could be seen a users own faulth. )
so besure Router is update with Firmware or IOS to newest version depend what hardware use ofc.

also look like DNS issue, but only you can test this, its not clear what 118 is maybe steam support knows.

105 issue look like a DNS problem lookup from steam )

not sure look like DNS issue. ( copy from other user

I should point out one more caveat: 105 does not absolutely mean ad blocker problems. It means the DNS for Steam failed to resolve. You could try the following:

Press the Windows Key + R to open the "Run" prompt
Type "ipconfig /flushdns" and hit enter


Fairly small chance this will resolve your problem, but it can't hurt to try. You should also make sure that Steam is allowed through any firewall you run.


alos this should fix itself after router reboot and wait 3minuts and turn on pc.
same as a reset, unless you have fiddel with DNS cache. or something did.

dont forget static router is not best solutions anymore. things change and is user own problem.

I've tried quite a bit of DNS troubleshooting, and haven't gotten anywhere yet. I'm sure it is some sort of layer 3 problem.

As far as static router I'm not sure what you mean. Do you mean a static host IP from the ISP for my entire home network? I don't really have much choice there nor am I sure that would matter unless Steam is specifically blocking my IP. Do you mean static routing within my internal network? I don't really do much of that, I have a few DHCP reservations, but nothing permanently static. I do have a couple of statics, but nothing I do Steam with.

I think we're on the same page with it being a layer 3 issue, but I doubt if I call the ISP they'll have any idea what I'm talking about or how to fix it. It's definitely not a damaged line somewhere, there are redundancies for that, and I would have received an alert from my work as it is a small town, one of our systems would've recognized an outage of sorts. I'm guessing it's more of an issue with the routing to the local steam server within my region, but I can't find a list of steam host IPs to ping in order to troubleshoot that.

Windows troubleshooting would be pointless I feel as it's happening on all devices, Windows and otherwise.

I might try factory resetting my modem after I back it up to see if that does anything, but I hadn't made any changes previous to it not working. I've also looked through every setting within the modem in granular detail. The only network related work I've done is build some Vlans on a layer 3 cisco switch, but it is air gapped from my network, I was working on it through it's console port I have since unplugged it. I also did some work on a fortinet 60C router that I had on my network for a brief period of time (it did reek some havoc as I had forgotten to disable the dhcp and had dual dhcp hosts for a few hours but that's since been resolved).

static router is just a term that hold router to what you type in , problem with those router is then ISP change ip or dns then you still point at wrong dns server , the other have many terms , most call them NAT routers other use automatick setup , a more custom friendly way to guide new user to fix isp wan and setup rest for them, i recommend last one and enable dhcp at own local net, this solve most issue for private person.

layer 3 is router
layer 2 is switch as default

you still need to terminate it, as i recall old basic it read every line in config file and even not active its still enable its interface and even the protocol is down or up, and line are down.

dual dhcp is not the problem you can have router 1 to wan and router 2 to router 1, with diffrent network ID , but then you neet to tell router 1 hey another private ip net at router 2,

dhcp scope is not a issue , but you should make them reseved, reason is then some take the ip and servsar cant use it then all hell break loose i do same on my wifi move them up in scope out of them way from normal ip adr. and reason is just fast idea not part or cable net. sure detail and dont matter, untill you see several units pop in and get adr and gone agian on own network.

a short syntax, it looklike dns pc cant get right gateway dhcp with dns server or isp change something or you point at wrong dns , or ofc, last option ISP have bug or wrong dns adr. in your config file.

try own entry add dns 8.8.8.8 , and i bet you already know this, and who it is.

worst case bypass own router and use laptop in wall plugg to test what is working or not. and get each router fixed step by step.

[Frank Spasic]

I've tried the google dns of 8.8.8.8.

My switch is a cisco 3850 which is layer 3 as well, but I'm not using for this.

I'm not sure what you're saying abot the dhcp, but that has nothing to do with this issue as I'm not using anything out of the ordinary. I'm unable to bypass the router itself as my connection is an SC fiber connector from the isp tht feeds directly into the residential gateway.

Assuming there were issues with my ISP it seems I would see something wrong with some other websites, but literally nothing else is presenting an issue. My household consumes massive amounts of data compared to an average user, and literally everything except the steam store works perfectly fine.

Yea, tuff luck lad

try use a laptap at wall plug , to determine , isp issue or own network. ( i cant say it more simple then that )

[Frank Spasic]

How would that differentiate ISP or own network? My wall plugs are all part of my own network. I think possibly you live in a region where that means something different or ISP is different. My ISP comes in on a fiber connection to a residential gateway or modem via an SC angled fiber connection... I can't say it more simple than that.

Possibly you mean have a PC contact the outer world using my ISP provided IP address as its host address bypassing the home network and subnet? I built all the 'wall plugs' myself, they are all part of the home network vlans I've created.
