I've been running an LE client (official one, dehydrated, others) on various system for ~8 years, and the one time I had an issue with renewing was when (AIUI) the LE folks changed CDNs and so their responses were (slightly) different and dehydrated needed to be tweaked:

* https://community.letsencrypt.org/t/jws-has-no-anti-replay-n...

* https://github.com/dehydrated-io/dehydrated/commit/e4e712c03...

Other than that, never had an issue.
