I haven't been able to load into Reddit for the past couple days on Google DNS or Cloudflare. The only one that seems to work reliably is my ISP's DNS.

brave junco Nov 28, 2022, 8:39 AM

#

login to your front end and from the frontend's shell/ssh/console check to see if the dns resolves ... if it does then might be a firewall/gateway configuration issue

#

do other devices on the same network subnet and network pool resolve fine?

and out of curiosity are you using a VPN?

brave junco and out of curiosity are you using a VPN?

It works when I use a VPN

#

brave junco do other devices on the same network subnet and network pool resolve fine?

Um I'm not quite sure what all of that means tbh

#

I'm on a Google WiFi mesh

#

I've configured the DNS through their app

#

The mobile app works just fine but the browser version doesn't

#

I've tried all of my devices

#

Doesn't work on Windows, Linux, Android or MacOS

#

neat bronze I'm on a Google WiFi mesh

what ISP are you using?

#

do they utilize traffic shaping?

neat bronze Nov 28, 2022, 8:59 AM

#

brave junco what ISP are you using?

ACT

#

I'm in India

#

are you double natted?

neat bronze Nov 28, 2022, 9:01 AM

#

brave junco are you double natted?

Nope

brave junco Nov 28, 2022, 9:01 AM

#

its a computer, correct that cant access it, but you say mobile phone app works fine, correct?

neat bronze Nov 28, 2022, 9:02 AM

#

Yea the browser version doesnt work regardless of the device but the app does

brave junco Nov 28, 2022, 9:03 AM

#

is your ISP modem.... a modem and router 2-in-1 combo?

neat bronze Nov 28, 2022, 9:03 AM

#

Nah the modem was provided by the ISP

#

I have a TP Link Archer or smth to serve as the router

brave junco Nov 28, 2022, 9:04 AM

#

have you tried bypassing the mesh and just tried connecting through the TP link Archer to see if it works normal?

neat bronze Nov 28, 2022, 9:04 AM

#

Yea that works

#

But that's only cuz I use the ISP's dns on there

#

If I switch that over to Google then it doesnt load either

brave junco Nov 28, 2022, 9:05 AM

#

neat bronze If I switch that over to Google then it doesnt load either

even if you are directly connected to the TP link router and bypass the mesh?

neat bronze Nov 28, 2022, 9:06 AM

#

brave junco even if you are directly connected to the TP link router and bypass the mesh?

If I switch the DNS over to cloudflare or google yeah

brave junco Nov 28, 2022, 9:07 AM

#

so cloudflare and google dns work fine with reddit if you bypass the mesh and connect directly to the TP link router?

neat bronze Nov 28, 2022, 9:07 AM

#

Oh no they don't work even if I bypass the mesh

#

Only the ISP's DNS seems to work

brave junco Nov 28, 2022, 9:08 AM

#

what happens if you connect i directly to the ISP modem and bypass the TP link?

neat bronze Nov 28, 2022, 9:09 AM

#

It would just redirect me to the support page I think

brave junco Nov 28, 2022, 9:09 AM

#

it shouldnt, it should work

#

thats your front end

#

if it still does it then your isp might be traffic shaping

neat bronze Nov 28, 2022, 9:10 AM

#

Ohh

brave junco Nov 28, 2022, 9:11 AM

#

you should be able to access reddit with with any working DNS like cloudflare, google, isp dns, once you connect it directly to the isp modem.

neat bronze Nov 28, 2022, 9:11 AM

#

Hmm that seems like a lot of setup

brave junco Nov 28, 2022, 9:12 AM

#

you have a mesh setup, its going to be alot of setup

#

the more complicated, the more of a setup

neat bronze Nov 28, 2022, 9:12 AM

#

True

#

I'd have to call my ISP to access the modem itself I think

#

The fiber optic line comes in onto the roof of my house

brave junco Nov 28, 2022, 9:13 AM

#

neat bronze Hmm that seems like a lot of setup

connecting directly to the modem shouldnt be a hassle at all, its just plug the wire from PC to modem directly, should be easy

neat bronze Nov 28, 2022, 9:14 AM

#

brave junco connecting directly to the modem shouldnt be a hassle at all, its just plug the ...

Oh its just that I'd have to take my security stuff offline

#

In that case I think I'll just live with my ISP's DNS

#

I ran the DNS benchmark and the ISP's DNS is only second to Cloudflare so I'd be better off going with that than Google anyway

#

Thanks a lot for the help!

brave junco Nov 28, 2022, 9:16 AM

#

yup, im sure its probably a setting you have somewhere, but without narrowing it down its hard to know in a mesh setup, so just easier to start at the front and work toward the backend in my opinion

neat bronze Nov 28, 2022, 9:16 AM

#

Hmm yeah I just find it odd that this happened all of a sudden

brave junco Nov 28, 2022, 9:17 AM

#

but it involves times and effort to do all that which is up to you

#

auto firmware/app update most likely happened

neat bronze Nov 28, 2022, 9:17 AM

#

I've been using this setup for a little over 3 years now and I've never had a problem with it until 3 days ago

neat bronze Nov 28, 2022, 9:17 AM

#

brave junco auto firmware/app update most likely happened

Ah

brave junco Nov 28, 2022, 9:23 AM

#

neat bronze Ah

also manually changing the dns in the network appliance to correctly suit your needs and have it assign properly is a better solution than using a app, the app is just another layer to complicate things even more. good luck if you ever decide to look into it more
