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.
So when you are instructed to create an e.g. _acme-challenge.soluto.com TXT record, you would put _acme-challenge for “Name” in step 4, and the TXT record value as “Value”.
