    Hi,

    When we moved our site to a new faster server with more recourses ERR_HTTP2_PROTOCOL_ERROR started to appear. Our IT service provider blames the server, server blames the IT service provider. The domain server provider says, it cannot find any issue on this side, and the IT service provider says, that in previous server worked and it is no fault on his side. How to solve this issue. The site got slower instead of faster.

    The page I need help with: [log in to see the link]

    Hi @vadimpetrenko

    I understand that you are experiencing the ERR_HTTP2_PROTOCOL_ERROR after migrating your site to a new server. This error is usually related to the HTTP/2 protocol that your server uses to load your website.

    While it’s true that both your server and IT service provider play a role in maintaining the smooth operation of your website, it’s important to remember that issues can sometimes arise from the software or settings used on either end.

    Here are a few steps you can take to debug and hopefully resolve the issue:

    • Check your SSL/TLS configuration: HTTP/2 requires a valid SSL/TLS configuration on your server. Make sure your SSL certificate is properly installed and updated. You can use an online SSL checker tool to verify this.
    • Disable HTTP/2 on your server: If the problem persists, try disabling HTTP/2 on your server temporarily to see if that resolves the issue. If it does, a problem with your server’s HTTP/2 implementation may need to be addressed.
    • Check your CDN settings: If you’re using a CDN, check its settings. Some CDNs support HTTP/2 and can cause issues if not configured properly.
    • Consult with your hosting provider: If you’ve tried these steps and the issue still persists, it may be a more complex issue that your hosting provider needs to address.

    Remember that these are just potential solutions, and the actual solution may vary depending on the specific configuration of your server and website.

    Lastly, the site’s speed issues may or may not be related to the ERR_HTTP2_PROTOCOL_ERROR. If the above steps do not improve your site’s speed, I recommend conducting a performance audit to identify any potential bottlenecks.

    I hope this helps! If you have any further questions or need more assistance, please don’t hesitate to ask.

    Thanks!
