Site wont rebuild

I am trying to install a plugin as i have many times,

I edited the app.yml to include the link to the github repo, saved and input the command to rebuild.

After rebuilding the site is not functioning,ERR CONNECT REFUSED".

In the rebuilding log i see the following which i assume it indicative of the issue: ’
2019-01-29 17:07:13.425 UTC [68] LOG: worker process: logical replication launcher (PID 77) exited with exit code 1

Any advice/guidance would be hugely appreciated

-Adding: I did sftp in and download the yml file and put it in a validator, so its confirmed good and not simply bad formatting - the only change made was adding the new line the - git clone {{repo link}}

I think we might need more of the logs. But sometimes I need to reboot the server to rebuild


or if it still doesn’t work

service docker restart

And try another rebuild. It happens when something doesn’t close or restart correctly

Which plugin is it? Is it confirmed working with 2.2b10?

Does commenting the line out or removing it allow a rebuild to complete?

I am trying to install OpenID Connect Authentication Plugin;

The site was updated to the latest discourse bits and working fine however even commenting out the newly added plugin does not allow rebuild to complete successfully.

will report back soon after rebooting the machine and restarting docker

What if you comment out all plugins beyond the default docker manager?

If you’ve just upgraded to b10 you may be carrying another plugin which is incompatible and unrelated to the change you believe is leading to the failures.

Hmm troubling for me - I rebooted the machine, restarted docker, and commenting out all plugins except docker manager and rebuild, same results.

let me output the rebuild log to a text file and share; stay tuned!


Will generate the logs for you.

Not sure why i only get the following output from .launcher rebuild app > log.txt but here is what it gave me.

You have what appear to be non-official plugins.
If you are having trouble, you should disable them and try rebuilding again.

Discourse version at NOT FOUND

Just some general observations:

No need to expose 443 if SSL isn’t being used.

Unicorn_workers and db_shared_buffers are automatically set by bootstrap, but in your file they’ve been commented out. How long have they been set this way?

Was this installed by following the standard guide?

This was a digital ocean one-click installation, we do use ssl with a wildcard cert.

Ah, I would recommend reaching out to them then, we don’t support third-party packages here.


Will do - Thanks for the help/advice! :slight_smile:
