    Hello,

    This has been an issue for a week now. I tried eveything from changing DNS server, to clearing chrome cache, changing a bunch of settings, NOTHING is working. Only thing that worked for 10 minutes is resetting my modem, but then it does not load again after a short time. I disabled all anti virus also.

    Any idea how to solve this issue? The website works fine on my phonte data, this is a wifi/home internet problem:

    ERR_QUIC_PROTOCOL_ERROR

    Thank you!

    Hmm... try a different browser? It's working normally here using Opera and Firefox.

    If you haven't already, here's what Google had to say about it:

    The ERR_QUIC_PROTOCOL_ERROR in Chrome indicates a failure in the experimental QUIC (Quick UDP Internet Connections) protocol, often fixed by disabling this feature in Chrome flags, checking for extension conflicts, or updating browser security settings. It frequently affects connections to Google services and websites using specialized network protocols.
    Quick Fixes for ERR_QUIC_PROTOCOL_ERROR
    • Disable QUIC in Chrome Flags:
      1. Type chrome://flags in the Chrome address bar.
      2. Search for "Experimental QUIC protocol".
      3. Change setting to
        Disabled and relaunch Chrome.
    • Disable Browser Extensions: Some extensions, especially ad-blockers or security tools, can cause this. Disable extensions one by one to identify the culprit.
    • Check VPN/Web Protection: If using a VPN (e.g., NordVPN), disable "Web Protection" or similar features, as they may interfere with QUIC traffic.
    • Clear Browser Cache/Cookies: Clear browsing data to remove potentially corrupted cache files.
    • Update Chrome: Ensure Chrome is updated to the latest version by going to Help > About Google Chrome.
    Other Potential Solutions
    • Test Network: Switch to a different network (e.g., mobile hotspot) to rule out ISP-level restrictions.
    • Firewall/Antivirus: Temporarily disable firewall/antivirus software to see if they are blocking the connection.
    • Update DNS: Set your network to use Google Public DNS (8.8.8.8 and 8.8.4.4).

    Yeah, certainly seems that way to me. If all else fails, perhaps a rollback to when it worked OK? :dunno: Sorry cant be of more help with your Chrome setup :sad: Maybe another member here who uses Chrome without issue can chime in with their settings :unsure:
