I have a main domain and Sub Domain in it, recently the subdomain SSL (Let’s Encrypt) got expired and I tried to renew manually. But I am getting an error like this “Challange Failed for domain app.domain.com”. Can you please help me with this issue?
The following errors were reported by the server:
Domain: app.domain.com Type: unauthorized Detail: Invalid response from https://app.domain.com/.well-known/acme-challenge/1ZRCzKfcZfZ3lstv6XFblgwd1pspxGy-w78U_jKvB4o [2400:6180:100:d0::40f:e001]: “<!doctype html><html lang=“en”><head><meta charset=“utf-8”/><link rel=“icon” href=”/favicon.ico"/><meta name=“viewport” content="
To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.
Already these records have been added.
