I’m using DavX5 with Nextcloud for contacts and events synchronization, for sio4.org organization, where is in use Debian jessie 8.5 and Certbot 0.10.2-1 (I don’t know at the moment if is it possible to upgrade Certbot to a next release, since “apt” does not find more recent versions).
Then, for other organization 3x1t.org, Debian stretch 9.6, and Certbot 0.28.0-1, and again DavX5 and Nextcloud.
My question is: on 3x1t.org, it is sufficient to accept the first certificate and the following (of the same domain) are automatically accepted at each renewal by DavX5.
On sio4.org, instead, at every renew, DavX5 show the renewed certificate signature and ask me if accept or reject it.
I’ve open this question on DavX5 forum too, and now here, since I seem to understand it depends to some extent on server-side issues.
Have you any suggestion?
Many many thanks!
