**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one
```
As it said I should read the former lines for more error messages, I checked the message in **./launcher rebuild app** and found the only more message is
```plaintext

And here is the docker ps that might help.

**Could you please help me？**

I checked meta, and found some perhaps similar answers, but I tried rebooted the server, and nothing happened.

> Hi, I’m attempting to install Discourse, but am failing so far. It appears that bootstrapping doesn’t want to… bootstrap? Anyhow, I read a couple of other threads about it and tried “./launcher rebuild app”, which gave the following output: WARNING: No memory limit support WARNING: No swap limit support Updating discourse docker Already up-to-date. Calculated ENV: -e LANG=en\_US.UTF-8 -e RAILS\_ENV=production -e UNICORN\_WORKERS=3 -e UNICORN\_SIDEKIQS=1 -e RUBY\_GC\_MALLOC\_LIMIT=40000000 -e RUBY\_HE…

Is it because this is a server in China, and now some of the websites are blocked by the great Chinese firewall?
* * *
## What’s more
It’s not only not rebuildable, but also the server encounters 502 Badgateway(nginx) error.
I checked the docker is running.
I restarted the discourse, rebooted the server, but still nothing happened.

The rebuild command produces a lot of output. You have not included it all, or enough to say where the problem may lay.
Checking, I see my last failed rebuild had 280 lines of output.

Hi, you asked for the whole message

and I found a very similar problem which was caused by the source of ruby china.

Line 2584 in your log file:

So you’re correct that this is caused by the RubyGem mirror you’re using.
* * *
Running the following should remove the bundler mirror config.
```plaintext
bundle config --delete mirror.https://rubygems.org
```
[Here is](http://bundler.io/v1.15/bundle_config.html#MIRRORS-OF-GEM-SOURCES) the official doc on using mirrors with bundler.

Thank you very much. I got all the problems done with the help of a Chinese friend.
That is because of the ruby source in China is not up to date.
And the solving is delete the line in app.yml
Rebuild you will solve such problems.
