SSL certificate problems when accessing

SSL certificate problems when accessing

We use SSL certificates from LetsEncrypt on all our websites. Recently their root certificate has expired and is replaced by a new one.

If you get errors, e.g. during git operations, like these:

fatal: unable to access '[some-repo].git/':
  SSL certificate problem: certificate has expired

# OR

fatal: unable to access '':
  server certificate verification failed. CAfile: none CRLfile: none

Then you have to apply outstanding updates to your operating system which should resolve the issues. See the following pages for more information:

If you cannot update your system you can temporarily disable SSL checks in git by setting the following environment variable:

export GIT_SSL_NO_VERIFY=true

On one older Windows machine I also had to update git.
