Hi,

Thank you for reaching out to us. I’m sorry that you’re experiencing issues.

What is your domain? After disabling the QUIC protocol, do you still receive a ERR_QUIC_PROTOCOL_ERROR or is it a ERR_HTTP2_PROTOCOL_ERROR? Does this happen when proxied to Cloudflare and not proxied through Cloudflare as well?

We look forward to your response.

Kindly,

everything was working fine, it started a month ago, i didn’t make any changes to the sites, i don’t know why and how it happens but this error keeps appearing

Hello,

We are also getting a similar error and disabling QUIC protocol does return an ERR_HTTP2_PROTOCOL_ERROR. We do not get this error when it’s not proxied with Cloudflare.

Thank you

What’s the domain @fred16 @Lili84 ?
Also, a netlog would be very helpful

We are also facing the same issue. It returns network error on some network especially mobile network. This error disappears by using VPN or pausing cloudflare.
