Watching this thread, please let us know if you found a solution, this problem is very annoying. We are using Let's Encrypt also, so having to manually revalidate several domains every 3 months is annoying and risky (sometimes the system isn't working or down, so risk not being able to renew in time). Even if we switch to a different SSL provider, they limit certs to 1 year now, so not like before where this was just a once every 3 to 5 year problem.
