Caddy run well via Firefox or Safari, but failed in Chrome and Opera

Help

1. The problem I’m having:

My website with https runs very well in Firefox and Safari. If I use Firefox to browse my website, it runs successfully, when I use Windows 11, MAC, iPhone. But when I use Chrome, Edge or Opera in Windows 11, I can not open my website.

2. Error messages and/or full log output:

Below log is from Chrome with F12(Dev Tools).

4. How I installed and ran Caddy:

I install Caddy on Ubuntu 22.04 follow Caddy offical website, not in docker.

d. My complete Caddy config:

very simple, I use Caddy as a reverse proxy,

host.abc.com {
        reverse_proxy host.abc.com http://home.dynamicdomain.com:8080
        log /root/access.log
        tls zhongfang@email.com
}

5. Links to relevant resources:

Thank you very much! I encouted an error while I saved my first post in Caddy BBS. Now I completed my question. Hope your help.

Please follow the directions to use curl -v to make the request. What is the output of curl -v ... for your URLs? Maybe use -L in your case too.

If the redirects don’t happen in curl then it’s a browser caching bug.

This looks wrong. You have two arguments to reverse_proxy so Caddy will load balance between those two, and the first one will cause redirect loops because you’re proxying Caddy to itself. Remove host.abc.com there.

Thank you very much. I have resolved my problem after remove host.abc.com.

I didn’t know that I am using load blance…
I copy config from answers from Bing. I am a newbie to Caddy.
