I configured my nextbox with Guided Dynamic DNS and a deSEC URL - which worked quite fine until now. The Let’s Encrypt certificate expired a couple of days ago, but the Nextbox did not automatically renewed it - which I assumed should be the case?
So currently my Nextbox can’t be reached via a secured connection and I just can’t find a possibilty to manually do the renewal…did I miss something in the docs? The running unsecured connection still works well but is blocked by some browser / applications.
In addition, now the Guided Dynamic DNS configuration fails for the reachability test, which also worked fine before. But an unsecured connection from outside is still possible, though.
For my settings: the deSEC URL xyz.dedyn.io can be resolved properly for IPv4 and IPv6, the Nextbox HTTPS/TLS config says it is activated…with the failed reachability test, though.
My FritzBox settings are set with all the needed port forwarding (IPv4 & IPv6), DNS-Rebind, DNS prefix IA_PD with DNS address IA_NA)
Any hints on this? How can I get my Nextbox to renew the Let’s Encrypt certificate?
