Theme

Expected behavior

Preview should run as normal.

Actual behavior

Localhost seems to be hitting some sort of rate limit - then I'm present with this screen - really hinders progress with work:

Verbose output

  Had to use pastebin as too long for here.

Reproduction steps

1. Launch theme server as normal

I can't really give much more than this because there's nothing that 'triggers' it - it just happens.

Operating System

macOS Tahoe 26.0

Shopify CLI version (shopify --version)

3.84.1

Shell

zsh

Node version (run node -v if you're not sure)

v24.7.0

What language and version are you using in your application?

I can't seem to find any reference of this in that issue?

Also seeing this regularly, very annoying

[ekwoka]

Hitting this quite a lot, typically when on a cafe wifi, but only after an hour or so.

Same thing on version 3.85.4

I am seeing this same "Your connection needs to be verified" error. I am working on a different location than yesterday so I thought it might have to do with that. I am now able to trigger it again by switching from corporate wifi to phone hotspot. Sure enough after a little browsing the big white screen with the unhelpful "your connections needs to be verified" appears.

Running shopify theme dev in verbose mode I can see the following:

[MaxDesignFR]

I am also seing this issue. It was working fine until this message appears amid of a working session. Tried to re-auth, but it does not fix this bug. I'm on my home wifi and nothing changed in my setup. Eventually, the message goes away after 1 to 10 minutes without me doing anything.

[jaowork]

When can we expect a fix?

[1-oh-1]

This is quite annoying. It seems to occur more frequently when saving theme files multiple times in rapid succession, or when viewing theme components that make several API requests. The easiest "fix" is to restart the theme dev server. Definitely some sort of rate limiting error - the console shows every requests returning a 429 error:

• 15:08:50 Request » GET 429 /collections/mens-outerwear/products/1587985
• 15:09:00 Request » GET 429 /collections/mens-outerwear/products/1587985

[mskraban1]

Got the same error. Restarting dev server doesn't fix this error always.
