My hosting is using AutoSSL with Let’sencrypt.
Because my website is behind CDN, so I can’t use the http validation.
I’m trying to use the TXT DCV DNS validation to renew my certificate.
But everytime I click the AutoSSL to run, the TXT challenge keep changed. and made the TXT record that I put into the DNS invalid
Click AutoSSL --> Validation failed with the TXT challenge written on the error --> I change the DNS record as the TXT challenge written in the log --> Click AutoSSL again --> the TXT changed again
as far as I know previously it takes hour or days before TXT challenge are changed right? now it changes on every click.
does the problem within letsencrypt server, or the autossl configuration in my hosting server?
