My Master Jenkins is running on an Ubuntu VM. Jenkins was installed via apt and the SSL termination takes place on an nginx, on the same server.
When I try to connect slaves, it does not work. The slaves, at least on VM level, report an SSL error.
The slaves in Kubernetes terminate immediately and I have no access to the logs.
How can I solve the problem with the SSL? My certificate is an official, purchased certificate.
