Caddy hangs trying to stop it

1. The problem I’m having:

I’m sorry you closed the thread linked below, since I’m having the same issue.
caddy stop hangs and does not exit.

2. Error messages and/or full log output:

I’m getting the following immediate response when trying to stop:

2023/09/20 19:19:41.985	INFO	admin.api	received request	{"method": "POST", "host": "localhost:2019", "uri": "/stop", "remote_ip": "", "remote_port": "56182", "headers": {"Accept-Encoding":["gzip"],"Content-Length":["0"],"Origin":["http://localhost:2019"],"User-Agent":["Go-http-client/1.1"]}}
2023/09/20 19:19:41.985	WARN	admin.api	exiting; byeee!! 👋

And then it hangs untill, some time later it throws:

Even if you repeatedly mention that domains should be left intact, unfortunately I’m not allowed to share the company I work for, so the localbluff and the whatever bit in and are redacted.
If you cannot bear with that, unfortunately I’ll have to get along without your help.

It looks like the second half of the help template is missing. Can you please fill that out so we can help you? Otherwise we’ll just be guessing.

Edited, I hope that’s enough.
It actually works great, it’s just when i try to stop it.

Ok, thanks – I’ll investigate. Looks like @Mohammed90 already took a look and pinged me with some clues… interesting!

Did you splice anything out of your logs, or is it literally just those 2 lines and then the error + panic?

Additionally, is anything else happening prior to this, like reloading config or similar? I’ll need the full logs and unredacted please.

unfortunately I’m not allowed to share the company I work for, so the localbluff and the whatever bit in and are redacted.

You company can pay for private support and I’ll be happy to work with you without having to share things publicly! Here’s our sponsorship plans, I’d recommend a Business or Business+ sponsorship: Sponsor @mholt on GitHub Sponsors · GitHub

Unfortunately I can seldom afford to help companies for free these days. (So I can get around to this eventually, but it might involve some guesswork and take a long time.)
