Problems renewing my certificate

I use an SSL certificate from Let’s Encrypt and it asking for renew until June, 23.

But, when I try to renew, the following message is showing:

Renewing an existing certificate
Performing the following challenges:
http-01 challenge for vivaovinho.shop

Cleaning up challenges
Failed authorization procedure. vivaovinho.shop (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from https://vivaovinho.shop/.well-known/acme-challenge/PfBGjR123JK1h81xyI89VUQoGoggdQgHynwXXFYuxHs [2606:4700:3032::681f:544a]: "\n<html lang=“pt-PT”\n\tprefix=“og: https://ogp.me/ns#” >\n\n\t<meta charset=“UTF-8” />\n<meta http-equiv=“X-UA-Co”

IMPORTANT NOTES:

I checked the DNS and it looks correct to me.

Could you help me?

It’s a little tricky renewing LE certs behind Cloudflare.

Out of curiosity, do you have “Always Use HTTPS” enabled in SSL/TLS -> Edge Certificates? If so, try turning it off. I believe LE needs to use HTTP to renew a cert via http-01.
