CI/CD run failing on SSL certificate problem

Hello, we are running recent version of Gitlab CE.
Whole GitLab instance is running on HTTPS, with valid GoDaddy wildcard certificate (I exported crt, pem and key file from pfx certificate I already had and placed them into /etc/gitlab/ssl directory).

Connecting to GitLab UI works just fine.

I added GitLab-Runner using gitlab-ci coordinator URL (I used HTTPS for that.)

Strange is, that command

curl https://myGitHostnameUrl

returns: curl: (60) SSL certificate problem: unable to get local issuer certificate.

CI/CD run then fails on : fatal: unable to access ‘https://pathToMyRepo/’: SSL certificate problem: unable to get local issuer certificate".

I also tried command git config --global http.sslVerify false, run is still failing.

Please, how can I proceed to get the run going?
