When I’ve seen this before it’s been on very old versions of the app and was due to some region specific variations in .net. Which version are you running?

If on the latest version and the problem persists, try updating your Let’s Encrypt account under Settings > Certificate Authorities > delete the existing production account and add a new one, this will generate a new account key (which is used when generating challenges).
