I keep getting NGINX errors regarding lua_load_resty_core…have tried it on two different servers with a fresh /config folder.

Using docker-compose:

services:
letsencrypt:
image: linuxserver/letsencrypt
container_name: letsencrypt
cap_add:
- NET_ADMIN
volumes:
- /home/letsencrypt:/config
environment:
- PUID=1001
- PGID=1001
- EMAIL=REDACTED
- URL=REDACTED
- SUBDOMAINS=REDACTED
- ONLY_SUBDOMAINS=false
- VALIDATION=http
- TZ=America/New_York
ports:
- 80:80
- 443:443
restart: always

relevant logs:

Thanks for your help, let me know if you need any further information, I’ve had this running flawlessly for 6+ months and have just now run into this issue.

Thanks!

I’ve got the same issue. My reverse proxy became unavailable, so I checked the log and this was the first [alert] and [error] that popped up.

The Lua errors are harmless unless you use Lua, which I’m almost sure you don’t.
@nholben The only issue you have are the error message?

@derekleeds
If your containeriis not working, the Lua errors are not the source of you problem. You should start a new thread detailing your problem.

Might want to give the proxy a little more time to initialize. I have all my proxies unavailable for like 30-60 seconds after these lua errors on letsencrypt container logs.

After that errors stay there but proxies return to work as normal.

The same behavior every restart of the letsencrypt container.
