Gitlab 8.7.0 - GitLab API access: FAILED: Failed to connect to internal API

I have a nearly fully functional Gitlab set up. HTTPS connection is valid and has proper certs. Using Nginx.

My issue is that when I tried to push/clone to Gitlab, it would fail. When I was originally setting it up, I brushed off this error message as everything else worked but clearly it’s important. I’ve searched through the entire first two pages of google, but none of the solutions seem to apply here. (They’re usually based on fault connections in config.yml like not setting http(s)://). I’m using letsencrypt for my SSL certs and they’re in the directory “/etc/letsencrypt/live/example.com/”. Am I using the proper file for ca_file in gitlab-shell/config.yml?

Hi there, any luck in getting to the bottom of your issue? I’m experiencing similar issues with a freshly installed 8.7.3 instance on Ubuntu 16.04. However, I only intermittently get this problem (~ 30% of the time). Just now I ran:

sudo gitlab-rake gitlab:check

first time success, second time failure. I’d rather it never worked or, of course always worked! It’s certainly enough to cause my Jenkins to develop a major hate for me. I really don’t want to go back to gitolite, but may be forced to soon.

I should mention I am trying to run unbundled nginx.
