502 Bad Gateway after trying to rebuild test-passed branch

I tried to rebuild app after I followed the instruction about this: Change tracking branch for your Discourse instance, but when I update the app.yml and rebuild the container:

git pull
./launcher rebuild app

I got the fatal error which shows:

Pups::ExecError: cd /var/www/discourse && git fetch --depth 1 origin tests-passed failed with return #<Process::Status: pid 140 exit 128>

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.

And the website shows:

502 Bad Gateway

How do I fix it?

The whole log is in here:

whole log.txt (18.3 KB)

It seems like the rebuild is FAILED, and I used the ./discourse-doctor, shows:

==================== SERIOUS PROBLEM!!!! ====================

app not running!

Attempting to rebuild

Are you using a proxy for outbound traffic? It does not seem to be working correctly.

My server is in China mainland, I have doubt that whether it was influenced by the GFW, make the rebuild action can not get the branch on Github?

Yes, my server is in China Mainland, and the update is always very hard, the default action can’t pull git from Github

That is the problem.

Lots of information here: Upgrade from within China fails due to git issues

I don’t know how to install a proxy in my server。。。
