There is not enough detail to understand the exact problem.
But, I see from your prior post (link here) you had a custom ACME client. After you updated dehydrated to 0.7.1 did you apply all your custom changes to it?
I also see you got a wildcard cert on the staging system for s301.ilya.cf. How did you get those certs? And, what domain are you having problems with?
