Synology - Cannot issue a certificate mittra.me or books.mittra.me

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=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: mittra.me

I ran this command: Add a new certificate >> Get a certificate from lets encrypt >>

It produced this output:The operation failed. Please log into DSM and retry.

My web server is (include version):nginx

The operating system my web server runs on is (include version): Synology DSM 6.2

My hosting provider, if applicable, is: namecheap

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): NA

Have you updated to the latest firmware?

If so, this will break the LE challenge.

Lets debug results show everything is okay?

Are you able to place a test-file in that challenge location?
