All of their self-signed certificates nur (HTTPS) expired.
we tried to certificate renew, it look like ok, but it wasnt, old certificate is still there.
we tried to create new certificate with replace, but we had error "internal error-multiple certificates with matching subject were found in the database. please delete duplicates."
we tried to delete old certificate, but we had error "unable to delete certificates that are associated with a protocol"
we tried to use CA certificate also for HTTPS, looked like ok, it started new but after restart was everything like before.
