Research direction

Start with haproxy-certbot/docker/start.sh at line 52 and reproduce the failure using docker-start-services.sh with the documented Docker Compose setup for ThingsBoard 3.3.4.1 on Fedora 36. Inspect the iptables error and verify the container no longer enters a restart loop under the reported setup.

Written by the indexing model from the issue text.

Description

When running the haproxy-certbot container (via docker-compose or otherwise), it does not start properly and instead enters a restart loop. This is all following these docs for version 3.3.4.1 on Fedora 36.

haproxy-certbot container logs from running using docker-start-services.sh from the Thingsboard repo:

iptables v1.8.4 (legacy): unknown option "--set-mark"
Try `iptables -h' or 'iptables --help' for more information.

Here is the line from the start.sh script that seems to be causing the issue:
