can you provide more info?

Walshy•4/11/25, 9:18 AM

are you getting an error? if so, what?
if you aren't, what do you see?
what's your account id?

ArticBladeOP•4/11/25, 12:27 PM

The error is "Could not create remote preview session on your account"
my account ID 456951ed65894172e1a74c3fbda9a815

Im just trying to run the server and im getting this error.

Tait•4/11/25, 2:27 PM

I'm experiencing a similar issue. Just started today. I can't tell if I broke something ornot. Previously I would experience the "Could not create remote preview session on your account" issue intermittently but today it's constant.

@ArticBlade in the past removing items that don't work with --remote (like queues) would fix this but I'm now running into this when I have no queues in my project.

Tait•4/11/25, 2:29 PM

Is there some local state that could be blown away that might reset things and fix this? Perhaps in .wrangler/registry ?

ArticBladeOP•4/11/25, 2:33 PM

My code has no changes yet this happened which leads me to believe it's on cloudflare side. Maybe wrangler requires a different way to communicate or something now.

Tait•4/11/25, 8:29 PM

This just started working for me again.

ArticBladeOP•4/12/25, 7:42 PM

Yea same so it was indeed a cloudflare issue.

Keavon•4/15/25, 1:27 AM

I'm also receiving "Could not create remote preview session on your account" right now. Zero code changes on my end.

I first encountered it a few days ago. Then yesterday it had fixed itself. But now, today, it's erroring again.

I get this whenever I run my project and turn off local mode with the LL key.

Christopher•4/16/25, 6:29 AM

Is it a private thing or can I send it here?

Walshy•4/16/25, 6:29 AM

could someone also please share debug logs (WRANGLER_LOG=debug WRANGLER_LOG_SANITIZE=falseWRANGLER_LOG=debug WRANGLER_LOG_SANITIZE=false) - remove your auth token and email me walshy@walshy@

CChristopher Is it a private thing or can I send it here?

Walshy•4/16/25, 6:29 AM

you can send here, you can also do /link-account and i can grab it that way

Christopher•4/16/25, 6:29 AM

Christopher•4/16/25, 6:31 AM

Where does this go sorry? Doesn't seem to be cmd params

Walshy•4/16/25, 6:31 AM

WRANGLER_LOG=debug WRANGLER_LOG_SANITIZE=false wrangler dev --remoteWRANGLER_LOG=debug WRANGLER_LOG_SANITIZE=false wrangler dev --remote would be the full command

Christopher•4/16/25, 6:32 AM

Ah! I was close lol

Christopher•4/16/25, 6:32 AM

mmm, Powershell doesn't like that

Walshy•4/16/25, 6:34 AM

hoping this linkedin post is right https://www.linkedin.com/pulse/how-set-environment-variables-using-powershell-tutorialspoint-hkcsc

try

$env:WRANGLER_LOG = 'debug'
$env:WRANGLER_LOG_SANITIZE = 'false'
wrangler dev --remote

$env:WRANGLER_LOG = 'debug'
$env:WRANGLER_LOG_SANITIZE = 'false'
wrangler dev --remote

Christopher•4/16/25, 6:34 AM

Discount Facebook for the win; we have logs

Christopher•4/16/25, 6:36 AM

oh you're going to love this

Christopher•4/16/25, 6:36 AM

Getting a log file for you now, but I'll give you a hint: it starts with 4 and ends with 4

Walshy•4/16/25, 6:37 AM

Hmm

Christopher•4/16/25, 6:39 AM

Would this be a cause?

Walshy•4/16/25, 6:39 AM

Oh I have a theory..

Walshy•4/16/25, 6:39 AM

nah that should be fine

Christopher•4/16/25, 6:39 AM

Love a good theory, let's hear it!

Walshy•4/16/25, 6:47 AM

Ok looks like there's a bug in something new we're rolling out

if you enable

workers_dev = true

workers_dev = true

it should fix it for now

Christopher•4/16/25, 6:48 AM

All good, I tested in prod like a true dev should and it was fine; hopefully it will be fixed globally next time I need to make a change. Thanks for looking into it

Keavon•4/16/25, 6:59 AM

Let me know if I should also test it and send you my results

Walshy•4/16/25, 7:46 AM

You should be good, can do this for now as workaround

Walshy•4/16/25, 7:46 AM

Put up PR to fix, hopefully will roll out tomorrow

WWalshy Put up PR to fix, hopefully will roll out tomorrow

Keavon•4/16/25, 7:46 AM

Great, that means you found and fixed the root cause in your system's code?

Walshy•4/16/25, 7:47 AM

yep

Keavon•4/16/25, 7:47 AM

Awesome, that's what I love to hear

Keavon•4/16/25, 7:47 AM

Out of curiosity, did it affect many people or were we some obscurely small subset for a particular reason?

Walshy•4/16/25, 7:48 AM

it impacts only those who are using workers.dev for the preview (meaning, no routes attached) and have no Workers published on the workers.dev

Walshy•4/16/25, 7:48 AM

So, small subset

Keavon•4/16/25, 7:49 AM

Got it, so basically just those of us who are following the intro guide for setting up a small project (as is the case for me— I'm using it to view and curate some D1 database values but not actually put them on the public web)— but not yet deployed it.

Christopher•4/16/25, 11:08 PM

No dice with or without workers_devworkers_dev it would seem :/

Christopher•4/16/25, 11:10 PM

Ah, enabling it in the dashboard as well as the config fixed it, for now

Walshy•4/17/25, 5:41 AM

Fix will roll out today

WILDE•4/24/25, 10:02 AM

Hi! I've just came across this post because I am having a similar issue. Yesterday I could run my worker with

yarn wrangler -e dev dev --remote

yarn wrangler -e dev dev --remote

But today I am getting a 1104 error. Nothing changed in the code...

Walshy•4/24/25, 10:12 AM

please make a new post, that's a different thing.
