No idea what is going on, please help:
$ docker run -d --restart=unless-stopped
$ docker ps
$ http https://localhost
http: error: SSLError: HTTPSConnectionPool(host=‘localhost’, port=443): Max retries exceeded with url: / (Caused by SSLError(SSLEOFError(8, ‘EOF occurred in violation of protocol (_ssl.c:1129)’))) while doing a GET request to URL: https://localhost/
The output of docker logs 4e99d522cd2c will help here. And probably docker info.

docker logs is an archive of 113K, i did not see a way to attach it. Anything in particular i should grep?
It should be repeating as it tries to start and can’t, so the last 10 lines or something before it exists would help. Otherwise, use pastebin.com or gist.github.com .

i noticed that the log file did not include errors…
i redid the output with a better capture…
It is probably because of
I0719 12:25:32.163200 51 conntrack.go:103] Set sysctl 'net/netfilter/nf_conntrack_max' to 524288
F0719 12:25:32.163217 51 server.go:495] open /proc/sys/net/netfilter/nf_conntrack_max: permission denied
This was changed in a recent kernel, setting this manually on the host before starting the container or downgrading kernel (or using a supported OS, e.g. 20.04)
