Due to the fact that updating of DNS TXT records takes a while, every time I have to renew the certificate for my *.domain.tld, I have to wait around 10-15 minutes for the record to propagate and - of course - for letsencrypt to also read the TXT entry.
Since I am using more than one NS, is there any way I could use only one of them for validation and point certbot to that NS? I have 4 NS from which 3 of them are in US and one in Europe, therefore propagation takes some time...
Or is there any easier way to renew the certificate automatically?
Thanks for helping!
