SSL certificate problem: unable to get local issuer certificate

Hi all,

This is my very first post here, let me tell few words about myself.
10y+ exp programmer, mostly databases but also python and data engineering; linux exp more than 20y but mostly personal usage (and debian-based distros).

Now SUSE linux is our main distro at work and from the very beginning faced unusual issue on one of our servers (others work fine).

Could you please tell what else should I post here to get your advise?..

Alas. These are the openSUSE forums, not the SLE forums. That is also why you choose for OTHER VERSION, because you could not find your SLE mentioned.

Better go to https://community.suse.com/
