Docker acme.sh without dns challenge

[thesefer]

Hi, I am trying to issue certificates with an internal ca on a synology nas. Unfortunately the dns challenge is no option and all guides are written for this type of challenge.

I followed https://www.christosgeo.com/2022/02/03/renew-lets-encrypt-certificates-on-synology-using-acme-sh/ up until the point where I have to issue the certificate. Port 80 is blocked by nginx of synology, so the only option would be the --httpport xxx challenge. For this I would need to change the /etc/nginx/nginx.conf and the location ^~ /.well-known/acme-challenge to proxy pass to the port specified.

But if I change this config, would it survive a restart and/or synology updates? What other options do I have here (beside DNS, again this is no option)?

Went with the webroot and local install variant so I dont have to mess with potential nginx config loss.
