After changing an expired SSL-Cert on a zabbix agent2 monitored Client with template "Website certificate by Zabbix agent 2", we get a "Problem" with the newly added cert.
Problem description is "Cert: SSL certificate is invalid" with the following description: "SSL certificate has expired or it is issued for another domain.".
Looking deeper in this issue, we get "failed to verify certificate: x509: unhandled critical extension"

Steps to reproduce:

1. Add new certificate
2. Try to verify validity

Result:
failed to verify certificate: x509: unhandled critical extension
Expected:
A valid cert
