certbot no longer working?

Got an email this morning from LEt's Encrypt (perhaps their last?) that 
certs were to expire soon.

Checking logs, etc. seems like certbot was working fine for quite a 
while, with the last renew bring in December.  Expires in March.

No problems reported by apachectl configtest  or  apach2ectl configtest,

But /var/log/letsencyrpt.log shows, in part

. . .

I think these entries may be due to attempting to run certbot --apache 
from command line.  running certbot alone yells at me saying it could 
not configure the webserver.

Some place to start?  Obvious cause?

I configured this some time ago and, disuse and aging brain, leave me 
without a clue, currently.
