Yup, that's what DNS does

Kasumi•2/19/25, 2:55 AM

Was there a DNS outage?

Kasumi•2/19/25, 2:55 AM

MMattIPv4 Yup, that's what DNS does

PuffDragon•2/19/25, 2:56 AM

okay ive created an A record for example.com [that works]
but when i try to create work.example.com as an A record, it just shows 'work' on the list

MattIPv4OP•2/19/25, 2:56 AM

yup thats how itll show

PuffDragon•2/19/25, 2:57 AM

ok gotcha

Kasumi•2/19/25, 2:57 AM

Matt do you know anything?

MattIPv4OP•2/19/25, 2:58 AM

Alas no, my two brain cells have very few thoughts

MattIPv4OP•2/19/25, 2:58 AM

But seriously, no, no other reports of DNS issues

Kasumi•2/19/25, 3:00 AM

MMattIPv4 But seriously, no, no other reports of DNS issues

Kasumi•2/19/25, 3:04 AM

Others had this issue too looks like it was because of the Maintenance in FRA I guess

Kasumi•2/19/25, 3:05 AM

Just a bit weird it didnt re-routed or was there an issue / problem too? :thinkHeadSideWaysCutePondering:

PuffDragon•2/19/25, 3:06 AM

thanks @MattIPv4 appreciate it

Will the edge certificate with a monthly fee of 0 yuan be automatically renewed?

Can anyone here help a n00b with custom domain issues on icloud, or should I just Ask Jeeves?

Don't ask to ask, just ask

Set up a custom domain for a potential business through Cloudfare registrar. Linked said domain to my personal iCloud account. As business took off, emails became more difficult to organize and I needed visibility of ONLY the business emails, so I created a separate iCloud account for the business, gave domain permissions to the new iCloud account. Reverted former account back to original email as primary; however, the custom email that I created is still shown as "default email" under the personal iCloud account. I'm unable to link this custom email to the business iCloud account, as it says already in use. Cannot figure out how to remove it from "default email" under the former iCloud account- any help is appreciated. Have already been on the phone with apple... no solution there.

Ok, I don't need to activate the auto-renew button, it will execute itself?

My worker handles about 30K requests a day and every now and then (2/3 times a day) I get an client disconnectedclient disconnected error.

Does this means simply that a user closed a tab while a request was still processing? It's an AI app which uses streaming, so streams can take even 30 seconds, I wouldn't be surprised if someone would close the tab

cosbgn•2/19/25, 12:09 PM

Just trying to understand if there is a better way to debug this error or if my understanding is correct and I can safely ignore it

WTDawson9•2/19/25, 1:21 PM

Yeah, I kept on getting notifications a while ago that my tunnels became degraded

JustinNoel•2/19/25, 1:25 PM

I finally got a chance to use the new domain transfer tool to move some domains to a different account. I'm so glad that Cloudflare finally got this done.

Thanks for all the effort

and for putting up for my previous complaining

Hi!

GuillaumeLakano•2/19/25, 4:48 PM

Hi ! I don't see any report on #status / cloudflarestatus.com about Snippets problems.
We cannot save or deploy our Snippets ( PRO plan )
Even the default snippets proposed
When we arrives on the editor, before doing anything we got this error: API Request Failed: GET /api/v4/zones/xxxxxxxxx/snippets/edge_preview (503)
And on save as draft: API Request Failed: PUT /api/v4/zones/xxxxxxxxxxxxxxx/snippets/basic_auth (503)

Probably temporary

Kimbo•2/19/25, 7:59 PM

Hey guys!
I'm working on an app that uses WebSockets, and it's proxied through Cloudflare. It seems like CF closes WebSocket connections after 90 seconds if the client isn't sending data, even though the server is sending regular pong responses.

Would I be correct in thinking that CF only considers client-to-server traffic when deciding whether to close the connection?

Laudian•2/19/25, 10:14 PM

I started a websocket ~15 minutes ago and it's still active. Does Chrome have any built-in keepalive for websockets? I don't think it does.

Kimbo•2/19/25, 10:32 PM

I'm logging received pong messages server side, (dev env, local, no proxy), so the client (Chrome) is definitely responding here. I thought pong was a core part of the WebSocket protocol?

Laudian•2/19/25, 11:03 PM

You're right. My server actually sends a ping every 20 seconds. If I increase that to > 100, the connection is closed.

Isaac McFadyen•2/19/25, 11:27 PM

You likely want to implement application-level pings.

Isaac McFadyen•2/19/25, 11:27 PM

I forgot where but I was recently reading that sometimes the protocol-level pings aren't enough.

Isaac McFadyen•2/19/25, 11:27 PM

A simple pingping text message should do the trick. You'd just need to modify your server code to ignore that message.

Isaac McFadyen•2/19/25, 11:28 PM

Ah, here we go. Python docs but this is applicable in general:

https://websockets.readthedocs.io/en/stable/topics/keepalive.html
Browsers don’t enable a keepalive mechanism like websockets by default. As a consequence, they can fail to notice that a WebSocket connection is broken for an extended period of time, until the TCP connection times out. [...]

Unfortunately, the WebSocket API in browsers doesn’t expose the native Ping and Pong functionality in the WebSocket protocol. You have to roll your own in the application layer.

Isaac McFadyen•2/19/25, 11:29 PM

It is but if Chrome doesn't expose it there's not much we can do aside from sending our own :NotLikeThis:

Isaac McFadyen•2/19/25, 11:30 PM

Curious that the user is receiving pongs though, these docs seem to suggest Chrome doesn't send them

Isaac McFadyen•2/19/25, 11:30 PM

Maybe the server is sending pongs but Chrome isn't sending pings?

Kimbo•2/20/25, 12:55 AM

Hmm... this certainly appears to be chrome responding with pong.

Kimbo•2/20/25, 1:55 AM

From what I can tell, CF's proxy does not recognize WebSocket ping/pong frames. It seems to consider a WebSocket connection dead if no application-level messages are sent, even if the server sends pings, the client responds with pongs, and the server successfully receives them. CF ignores these keep-alive signals and still terminates the connection after 90 seconds.

Kimbo•2/20/25, 2:06 AM

I feel this should be more explicitly documented. The 'Best Practices' section suggests implementing keepalive, but it doesn’t state that it’s required to prevent CF from terminating the WebSocket connection after 90 seconds. This could lead to confusion for developers who assume standard WebSocket ping/pong behavior is enough.

Edit: to be more precise

Cloudflare supports proxied WebSocket connections without additional configuration.

Isaac McFadyen•2/20/25, 2:26 AM

From the screenshot you sent it doesn't look like there are any pings, only pongs

Isaac McFadyen•2/20/25, 2:26 AM

Is your server replying to what Chrome is sending there?

Isaac McFadyen•2/20/25, 2:26 AM

It should reply within 20s or the connection is considered dead per RFC

Kimbo•2/20/25, 2:31 AM

Please do look at the screenshot more closely, it does show the server sending ping, and the client sending back pong. Despite this keep alive most definitely working, CF proxy kills the connection. I am not the only to have hit this, as I have seen other apps having to add an app level keep alive just because of CF.

Isaac McFadyen•2/20/25, 2:57 AM

Ah yeah, apologies I just missed that.

Apoc•2/20/25, 5:59 AM

Does anybody know if it's possible to disable Enterprise Bot Management for a single subdomain? We have requests going cross-zone, and the __cf_bm__cf_bm cookie is causing our Tiered Cache implementation to be skipped because there's a Set-CookieSet-Cookie header that we have zero control over apparently.

Apoc•2/20/25, 6:16 AM

It doesn't as long as the requests are in the same zone

Apoc•2/20/25, 6:16 AM

And yes, we're on enterprise

Apoc•2/20/25, 6:18 AM

That's my assumption as well, but I also see it the other way around. It's a different zone, so the rules basically act like it's coming from the public internet, so I get it. But it's still incredibly annoying

Yup, that's what DNS does
