Hi,
i just reverted the patch in
/var/www/imscp/engine/PerlLib/iMSCP/OpenSSL.pm and it works
again.
For an newer version of certbot under Debain Bullseye this works:
https://gist.github.com/bmatth…b2e52ccdbc905aed73d9ca59c
# certbot --version
certbot 2.11.0
but its not necessary at the moment, or what ?
