Shopify store "Site can't be reached"

[MyCsPiTTa]

About 25% of the time I try to open my store I get the below error. This can be any store URL - e.g. Homepage, Product Page - but strangely it also happens with Shopify Admin itself. 

This is on Chrome. I've tried Deleting All Browsing Data, and it doesn't help. 
Sometimes opening in Incognito works, but now always.

What does always work is turning my VPN. I don't even need to click the URL again - it just refreshes and loads successfully. Then it continues to work, even with VPN  turned off. Until the next time,, that is...

I know this is probably a issue on my end. But its ONLY happens to Shopify, both frontend and backend. No other webpages are affected.

Any ideas what it could be?

Hi @MyCsPiTTa ,

Could you please try to

1. Disable QUIC in your browser by
   1. Open Chrome and type chrome://flags in the address bar.
   2. Search for "QUIC".
   3. Find "Experimental QUIC protocol" and set it to Disabled.
   4. Relaunch Chrome.
2. If this works, it means your LSP may not support QUIC, I would suggest you to contact your ISP regarding this problem.

Please let me know if this answer is fulfilled and please let me know if you have any other questions

Kind regards,

Den from FlashWombat

Thanks for sharing this, I can imagine how frustrating that must be, especially when it affects both your storefront and your admin access.

Since turning on your VPN fixes the issue (even temporarily), it sounds like it might be related to your network’s DNS routing or how your IP is being flagged or cached by Shopify’s CDN (Content Delivery Network). It’s odd, but not unheard of, especially if your ISP is having trouble resolving certain requests to Shopify’s servers.

Try switching your DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1)

If you’re on a dynamic IP your IP might be getting rate-limited or temporarily flagged by Shopify’s edge network.
