Discord not displaying (preview) images hosted on CPanel

should have worked but still didn't

Unless you've changed it afterwards, that's not going through BunnyCDN. That's directly to your hosting.

media2.thechemicalworkshop.com is going thru bunny

So dc2 is in DNS, it's not loading, but I also visited this before and this could be DNS issue - no idea which one Discord uses and for how long it's cached there.

dc1 is hardcoded in BunnyCDN to avoid DNS problems...

Which comes back to my original point that I wrote in this post: https://lowendtalk.com/discussion/comment/3626235/#Comment_3626235 - Discord is likely caching that subdomain as "not working", hence you should test with a never used subdomain and proxy it through Bunny.

let me make a brand new subdomain of thechemicalworkshop.com and route it thru bunny

discord never saw this subdomain, routed thru bunny*

JabJab

Nope, not loading.

Do you even see request in logs? Like I've run this in messages - dc2 should have log for "DISCORD_REQUEST_2.png" and dc1 should have log for "DISCORD_REQUEST_3.png" - but this should origin from bunny CDN rather than Discord proxy

spent yesterday like half an hour going thru logs and logs, can't find shit on cpanel, on bunny there was nothing either like an hour ago

Does it work through Jetpack

JabJab

Yes, 3rd party domain and 3rd party hostings works

I would guess this is Discord + RN problem (like rate limiting on theirs cpanel or something?) and first requests goes 404/500/timeout, discord marks the (sub?)domain broken and then when we try via any CDN it still thinks (sub?)domain is broken and never tries.

This however does not answers why the api subdomain works... but maybe answer is directly in subdomain and api is special whitelisted/not-rate limited thing?

Jetpack and imgproxy works just fine, atleast for me, so what i think is there is something wrong with server config, either webserver blocking discord origin or discord blocking the domain origin.

i'll ask racknerd, maybe they just know...
im tired of this issues, if i post a request "looking for cpanel" i'll update here

Hello, this is slightly hard to explain

Many websites and forums have image preview, which means if I post an image link it gets previewed for the user, this works on Telegram, Discord, some forums etc
The Server (Discord, Telegram etc.) fetches the image from Server (CPanel), caches it and displays it to the user. For security/privacy reasons, the user does not fetch the image directly.

I looked at all features, like CORS, hotlink protection etc, toggled them on and back off. Tried different subdomain, domain, routing thru CDN and more. routing image thru jetpack does work, but that's not my solution https://i0.wp.com/tcw.edu.pl/1.png

This used to work 2weeks ago normally without any issues

Is there a possibility you blacklisted discord servers on your end? 

The images work perfectly fine on browser, but when discord tried to fetch them, they are blocked, can't find logs about it either.

here is one of the images in question
https://tcw.edu.pl/1.png

I hope this can be resolved somehow

all we do is wait

https://media.thechemicalworkshop.com/TCWStandsFor/psychedelic fart/1.jpg

Uhh, because it has an invalid self signed SSL certificate?
It also results in a timeout when trying to load via Tor Browser, which is indicative that it may block Discord's IP addresses also.

CORS has nothing to do with it.

DeadlyChemist

Talked to support
TL;DR

They are aware as they seen this thread (good job ngl)
Their fixes didn't work (fair, could be discord)
They offered me free migration (might consider)

They lended me another node to test on, didn't expect that but will definitely test it.
After im done in few weeks/months testing, i'll let you know

possible i'll switch to other country/hosting (only for my pics) because germany is meh.

I'm not mad at RackNerd or anything incase people wanna hate, just annoyed at discord (again)

Money isn't an issue, it's like 20$ per year or whatever probably

Sorry to plug but I can give you a free test plan for a month or two in Canada. It’s DirectAdmin though

FatGrizzly

try loading the image via https://images-ext-1.discordapp.net/ , should be in the message, that might give you an insight too.

i'm not really a discord guy, during sometime around 2020 a guy mentioned this. I'll try contacting him and let ya know.

thanks !
so far does not look like it's working on the new cpanel instance, i'll try some other tricks to isolate it futher but yeah.... maybe my domain is banned? (I'll try to isolate it futher...)

try passing some dummy query strings too, like ?lalalalal=lellelao. should invalidate any caches on discord if any.

still not working, i guess it's an issue with RackNerd servers or CPanel? I might order some CPanel hosting just to test

new-ish domain (to discord) new subdomain
another picture
another server (RN/CPanel)

does not work

what we know:

• my domain/subdomain is not blocked
• possible that RackNerd or CPanel is fucked. I'm looking to test another CPanel instance

tonight will test my Direct Admin instance with myw

FatGrizzly

I'm 100% sure at this point it's RN. cPanel doesn't by default block Google cloud ips

JabJab

I can tell you that DA (with @hostslick) works
I don't have any access to cPanel, cPanel is expensive... but if those requests never ever shows up in your access.log without any magic rules/deny/firewall you have there - brand new, default vhost... then it's most likely blocked. Why would RN block Google Cloud? The fuck knows.

yeah, might open another thread, might go with DirectAdmin, but i need good country like netherlands

guess ping your fav host in NL or any "free country" rules (im not posting DMCA content)

Have you tried disabling ModSecurity and checked the WAF Logs in cPGuard?
