Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=welzijnsmasseur.nl), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: welzijnsmasseur.nl
I ran this command: Get a certificate via GUI from Synology NAS
It produced this output: Failed to connecto to Letâs Encrypt. Please make sure the domain name is valid.
My web server is (include version): Synology Webstation
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: mijndomein.nl
I can login to a root shell on my machine (yes or no, or I donât know): I donât know
Iâm using a control panel to manage my site (no, or provide the name and version of the control panel): Yes
The version of my client is (e.g. output of certbot --version or certbot-auto --version if youâre using Certbot): I donât know
On the same synology NAS I am running 2 different websites with a certificate from Letâs Encrypt without any problem. Only difference those domains are hosted by a different hosting company.
Thanks for pointing me in the right direction, I removed ipv6 settings at domain registrar under dns settings. Recreated the certificate and that worked. I will test it for some days and renew it in a few days. Then I will try to fix the ipv6 settings, but tried to find my ipv6 address, but canât find it. I used whatsmyip.com
The websiteâs using Cloudflare, and the IPv4 IPs are Cloudflare IPs. It appears theyâre failing to use the X-Forwarded-For header or whatever and reporting Cloudflareâs proxy server IP as âyourâ IP.
