Hello. I looked at some of the reported errors to see if this is the same, I see some related but not relevant (at least to a semi-technical person like me).
I have 21 subdomains for 6 domains, and am using standalone mode. OpenSuse LEAP 42.3, I’ve had this for many years (upgrading in place), just using it for some “home web servers and email server” for my family and a few friends, very low traffic volume.
After all, we all do want https everywhere, right?
I’m on DSL at the fringe (so, 6MB down and 800KB up). Yeah, I know, rather poor compared to some people…
Anyhow, when I put all 21 on the list of domains to certify for (the same list I always use), I will get “timeout” errors, but only for a random few. The ones that timeout will vary from attempt to attempt, sometimes just 2 or 3, sometimes 5 to 8 of them, never the same list.
In the past, I just try a few times and it eventually works. Today, after 5 attempts (or whatever the limit it), again with a random set of (sub)domains that failed, I hit a limit!!! Never saw that before.
I had once long ago tried the Apache Web Server plug, maybe a year or more ago, never got it to work (did I mention I was not an expert??). I also tried the webroot files version, maybe that worked last time, I can’t remember. I seem to remember I had issues at one time, and just used the standalone since, which used to work after a few attempts.
Is there a way I can perhaps “slow down the certificate issuance server” so that it does one at a time (serially), and waits a little longer? I suspect it is firing all domains in parallel at the same time, and falling flat with some because of my DSL bandwidth… Or my router (did I mention low budget?).
Or something else?
I could post logs here, if needed, just let me know the commands.

Thanks in advance.
