In which of these areas are you experiencing a problem?

Theme

Expected behavior

shopify theme dev should be executed correctly from my local environment to run the Shopify theme locally

Actual behavior

The shopify theme dev command fails with multiple errors (AggregateError, failed to sync with theme, etc...). I tried on 2 different computers, Windows and Linux, Node 16 18 and 20, downloaded latest and older versions of Shopify CLI package. I only got it working only a few times on a public Internet WIFI at a public place. I used 4G of multiple Internet providers but had the same issue. I'm not sure what to do else.
shopify auth logout and shopify theme pull both work correctly but not the dev command.
I also tried the following:

• I've tried to use a VPN with geographical location switch to UK and tested but got the same error (actually based in Tunisia).
• I disabled Firewall, VPN, antivirus and run again the command but still the same
• shopify theme dev --log-level=debug isn't working because it says "Nonexistant flag: --log-level:debug
• shopify theme clear-cache didn't work, it says "command theme clear-cache" not found
• Uninstalled and reinstalled shopify cli, but running theme dev resulted in the same issue
• Installed ngrok
• shopify config set tunnel ngrok isn't working, it says "command config set tunnel ngrok" not found
• ngrok http 8081 failed when run independently, please check the attachment for the error message

Reproduction steps

1. Just running shopify theme dev from my shell terminal

Shopify CLI version (shopify --version)

3.72.2

Shell

No response

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

From your verbose logs, it seems like it's actually successfully being setup, then some connection breaks afterwards.

There was a ticket a while ago where folks were being affected by Cloudflare re-routing. Seems like Tunisia is on the list of "Partially rerouted" https://www.cloudflarestatus.com/.
