I have an old Webhook that I want to delete. But when I go to delete it, things hang for 30 seconds and then a 502 Error pops up.
This dumps to console:
During this 30 seconds, one of my four ruby processes goes to 100% and stays there (I’m just monitoring this in `top`), so I think this is more of a bug or misconfiguration than an issue on my end (see note below).
Nothing is in my `/logs` page, but here’s my logs:
```plaintext
E, [2017-10-28T01:49:29.428736 #213] ERROR -- : worker=2 PID:28593 timeout (31s > 30s), killing
==> error.log <==
2017/10/28 01:49:29 [error] 209#209: *66829 upstream prematurely closed connection while reading response header from upstream, client: MY.IP.ADD.DY, server: _, request: "DELETE /admin/api/web_hooks/1 HTTP/1.1", upstream: "http://127.0.0.1:3000/admin/api/web_hooks/1", host: "forum.mydomain.com", referrer: "https://forum.mydomain.com/admin/api/web_hooks"
```
That’s after running `tail -f /var/log/nginx/error.log /var/log/nginx/error.log.1 /var/log/nginx/error.letsencrypt.log /shared/log/rails/unicorn.stderr.log` while inside of my web\_only container (my data and web containers are separated).
Note: I’m indeed having some problems elsewhere in my installation, much of it related to CloudFlare ([https://meta.discourse.org/t/cannot-save-theme-customizations-403-error-on-put/72854](https://meta.discourse.org/t/cannot-save-theme-customizations-403-error-on-put/72854)). But this is happening even without CloudFlare running at all, DNS or otherwise.
Thanks for any help. Not sure why this webhook’s so painful to kill - a short workaround would be to bump up the timeout??

Have you tried deleting that webhook from the rails console?
Something like
```plaintext
# ssh into your server
cd /var/discourse
./launcher enter app
rails c
WebHook.find().destroy
```
With “``” the id of the webhook which you can get when editing the details of the webhook.
- URL = `https://meta.discourse.org/admin/api/web_hooks/3`
- ID = `3`

Thanks, that worked!
Interestingly, it seemed to take less than 30 seconds to run that. Not sure why the web-based method took so long it had to time out.
Might be nice to get a longer timeout on some of these operations though?
Either way, much appreciated.
