How to use manual config Let's Encrypt in

Hello everyone,
I use a free hosting in Byethost, it allows me to add key, csr, and certificate manually in its cpanel. I would like to use Let’s Encrypt to get its free certificate because I can’t afford paid ssl and hosting for right now.

I tried to use three of domain verification types in already, none of them works.

My domain is: (this is a community service web that I am working on)

I use a manual verification by uploading a file at .well-known/acme-challenge, it was actually works, but when I want to get the certificate, it produced this output:

Domain “” challenge3 failed. Response from “” was: { “type”: “http-01”, “status”: “invalid”, “error”: { “type”: “urn:acme:error:unauthorized”, “detail”: “Invalid response from “\u003chtml\u003e\u003cbody\u003e\u003cscript type=“text/javascript” src=”/aes.js” \u003e\u003c/script\u003e\u003cscript\u003efunction toNumbers(d){var e=[];d.replace(/(…)/g,func"", “status”: 403 }, “uri”: “”, “token”: “omArxif0wUe8Vo9lHgsEuJcMvaM7_RXUGPtupr3Yu70”, “keyAuthorization”: “omArxif0wUe8Vo9lHgsEuJcMvaM7_RXUGPtupr3Yu70.DOUh9huHS0NML4EVWLumDE_XTScco8aRfqYU_zj9TeM”, “validationRecord”: [ { “url”: “”, “hostname”: “”, “port”: “80”, “addressesResolved”: [ “” ], “addressUsed”: “”, “addressesTried”: [] } ] }

Does anyone can help me on this? Thank you.

The website has some sort of “security” configuration. Your web browser gets the real file, the Let’s Encrypt validator gets a “checking your browser” HTML page, and one try I made got a 403 Forbidden error.

For example, here’s someone else with a similar issue:

I’m not sure what, if anything, you can do. Adjust the web server configuration, if possible, or ask your hosting company. :sweat:
