Let's Encrypt Unable To Renew On ASUS Router Due To Port 80 Closed


Let’s Encrypt Unable To Renew On ASUS Router Due To Port 80 Closed
I switched ISPs recently and now port 80 is closed and Let’s Encrypt is unable to renew.
Looking for a way now to circumvent this, any help would be greatly appreciated.
Receiving the following errors:
Aug 15 17:05:10 kernel: /usr/sbin/acme-client: https://acme-v01.api.letsencrypt.org/acme/new-authz: bad HTTP: 429
Aug 15 17:10:08 kernel: /usr/sbin/acme-client: transfer buffer: [{ “type”: “urn:acme:error:rateLimited”, “detail”: “Error creating new authz :: too many failed authorizations recently: see https://letsencrypt.org/docs/rate-limits/”, “status”: 429 }] (189 bytes)

Thank you ahead of time.



Whats your domain name? What’s your DNS provider? There are many clients for let’s Encrypt and one of those might support automated DNS validation with your DNS provider…

Thank you


Does this answer your question?



Sure… However, in this case I think you will have no option but switch ddns provider… (Since Asus built-in ddns only provides let’s encrypt via http-01 validation, and it requires to use port 80)
And asuscomm definitely does not support let’s encrypt validation via DNS…

Thank you
