Connection refused when running `backup` manually

[milanmlft]

I followed the documentation to run a local instance of remark42 and set it up with

REMARK_URL=https://localhost SECRET=123456890 ADMIN_PASSWD=password docker compose up

But when I try to run the manual backup with

docker exec -it remark42 backup -s remark

I get

remark42 v1.12.1-1f2500f-20230821T12:01:17

Any idea what might be going on and how I could resolve this? Thanks a lot!

Your container exposes http and not https, so REMARK_URL should be either http://localhost or https://remark42.example.com, e.g. the domain you are serving Remark42 externally.
