If you can access locally, it doesn't sound like a Traccar issue. You need to look again at your proxy setup.
The new version works for me without any issues.
Same setup: Traccar runs using the official docker image and Apache HTTPD is the reverse proxy for public access.
I can access it locally without problems, but from the reverse proxy, which I was able to access without problems until now, I can't. I haven't changed any settings, I've only updated the container.
Thanks
