[jason.gumarang]

Hi Community,
Currently, we are currently wordpress to manage our website.

my current cloudflare DNS settings is

cname www company.fi dnsonly

i also have a settings Always Use HTTPS enabled.

so, when i browse www.company.fi, it should redirect me to https://company.fi but i have this error instead.

ERR_QUIC_PROTOCOL_ERROR

hope you can shed me some lights. let me know aswell what information you need and will try to provide it.

A company.fi “ip address” Proxied
