certbot outdated ?!

For some weeks now, I got mail notices about certbot like this:

I've tried to upgrade certbot, but the very last Version I got is 1.1.0. It seems that it still use ACMEv1.
Will ISPConfig get an upgrade to support let's encrypt in the Futur (after June 2020)?

 

I've found a solution: https://www.howtoforge.com/communit...t027-0-need-upgrade-solved.83615/#post-398336

Seems that only outdated certificates cause this error-message

Yes, force the old certificates to use the new protocol, that makes error go away.
