i experienced a strange problem. my acme certification has been running fine for a long time but recently failed to renew certificate. Upon checking it seems that failure set upon authorization at dns@desec. My token has not been tampered with. ddclient.conf has same update password which is my token secret. ip address has been duely updated and i can verify at my account. Token still within valid period. My acme secret is exactly same as in my ddclient.conf file. Yet I tested with Api authorization with the same secret and still returned invalid token. I totally cannot comprehend what is going on. If ip address update is successful with same token secret how could authorization fail at all with api access?
