Access to SupremePen.com intermittently fails with ERR_QUIC_PROTOCOL_ERROR. QUIC is a network transport protocol (used by Chrome/HTTP3); this error often points to browser cache, network, or ISP issues rather than the site itself.
A responder could load the site successfully, indicating the store is online. Recommended checks: test in an incognito/private window to rule out cache; if it loads, clear cache and cookies. Try a different device and internet connection to isolate the issue.
Another participant with the same symptom reported the site worked over VPN but not via their ISP; rebooting the modem with ISP support resolved it. This suggests possible ISP routing or local network caching problems.
Support asked affected users for more domain context (connected or hosted by Shopify, transfer history) and advised contacting live support for account-specific investigation if issues persist.
Outcome: no evidence of a Shopify-wide outage. Likely localized caching or ISP/network issue. Status: guidance provided; original poster has not confirmed resolution.
Hello,
I am trying to reach my site: SupremePen.com and I get this error message when i attempt to go to the site:
The webpage at https://supremepen.com/ might be temporarily down or it may have moved permanently to a new web address.
ERR_QUIC_PROTOCOL_ERROR
I have the domain connected, so I am a bit lost why this is happening. Any help would be appreciated!
Hi, @ryanthetape .
Greetings! I hope your day is going well. I had a look at your website and had no issues accessing it. It sounds like you could be experiencing a cache issue. To know for sure, try viewing your site from an incognito or private browser. If the site is displayed, then it confirms a cache issue. To correct this, clear your browser cache and cookies.
If you are still not able to access your site, it could be an issue with your provider, or your device. To narrow that down, try accessing the domain from another device and connection.
In the meantime, since I was able to view your site I did want to let you know what a great job you’ve done! Are you using Oberlo? The reason I ask is it looks as though you followed the Dropshipping 101 course to a T! Great job!
I would love to hear more about how you plan to market your product. In case you weren’t aware, we have some great 100% free courses available to our merchants such as How to Brand and Sell a Winning Product. I definitely recommend you check them out!
I have the same issue.. how to resolved it?
Hi, @Hanan4
Thanks for joining the conversation!
I understand you are having issues with your domain. As each domain issue is unique, can you provide me more context on the issue you are experiencing? Is your domain connected to Shopify or is it hosted by Shopify? Did you transfer it from another platform?
If you are unable to provide more context I recommend reaching out to our live support team who can investigate the domain directly. Please find a link to the help center above.
I already had this issue yet.
Some time you need to reboot your modem completely. Is probably problem with waste of cache or other thing.
On my side, i have tested with VPN. The website have worked. But when i have passed through my internet supplier without vpn, it doen’t work.
Anyway, i have called my supplier, we have rebooted my modem and finally all work properly.
I hope this answer will help you
