I’m getting a ERR_SSL_PROTOCOL_ERROR in Chrome when trying to visit a page using 1.1.1.1 family. This doesn’t happen if I’m using a mobile network so I’m sure that it’s 1.1.1.1 that’s causing it. The site is:
I’ve tried using the help site that confirms I’m using 1.1.1.1
Can anyone suggest what the problem might be?
Thanks
Anyone know where I can go next with this?
Just bumping to try and keep this open, as I’ve not had any feedback yet 
I’m not sure what could be wrong, can you try to resolve the domain and post the results?

Thanks for trying to help @mvavrusa

It seems like the record returned by DNS is the same. Is the error triggered for this site or some other asset on the site?
It’s the actual page that’s causing the error:
Interestingly I’ve just discovered Firefox is returning a different error
Error code: SSL_ERROR_RX_RECORD_TOO_LONG
I’ve tried navigating directly to https://54.147.229.137 in Chrome which provides me with the “This site is not secure” but you can bypass to get to the site. This does load but Chrome thinks the certificate is invalid (I’m not sure how to figure out why it thinks it’s invalid - unless it’s because I’m not using the domain to access it anymore?).
I’m not sure what’s the issue to be honest. Since the DNS response is the same, and it works over a mobile connection, it might be a problem on the path or you might be routed to a different cache node.
Laods fine over HTTPS from my home.
Could be due to your ISP blocking something or there is some packet drop in between?
Make sure your server is configured to serve HTTPS content from the 443 port - whic from what I see and tested is working (your origin IP).
Does it mean you are currently not using proxy mode 
, rather either temporary switched to 
(DNS-only) or Paused Cloudflare for your domain?
Furthermore, seems your nameservers aren’t anymore pointed to Cloudflare.
Have you had a valid SSL certificate installed at your origin host / server before moving to Cloudflare?
When you were at Cloudflare, did your origin host / server worked over which TLS version?
And what SSL options have you had selected at the SSL/TLS tab? (Flexible, Full, Full (Strict) ...)
In between, have you tried clearing your Web browser cache, or trying to access via another Web browser, either via a Private Window, or using an VPN connection, or cellular (mobile, LTE, edge …) data (a different ISP provider)?
May I suggest to read this post:
Hi, thanks for your input - just to be clear I don’t own this site/domain etc
