Some users have cert issues while others do not

No. You have a valide certificate, so use it. The certificate has no information about the ip number.

But:

Your ipv6 doesn't work. I see, you have rechecked your domain (via https://check-your-website.server-daten.de/?q=arundelnewsnet.com ).

If you create a new certificate, Letsencrypt prefers ipv6.

But your ipv6 has timeouts, so creating a new certificate (in 60 - 85 days) would crash.

And it's also bad if a user comes via ipv6 - and has a timeout.

I have rechecked it and no luck. Should I show you the ipv6 definition?

Yep, share it.

Additional: Is there a firewall or something else that blocks ipv6?

Using online ipv6 ping tools your server doesn't answer.

Here is the SSL virtual host definition

Here is the ip6tables allowing 443

That looks ok. But I’m not so firm with ipv6 configurations.

If you use a tool like

http://www.traceroute6.net/

your ipv6 doesn’t answer.

But pinging your server works. Same tool:

Try now because it is working for me. The reason…I disabled ip6tables.

I don't need to recheck it, you have already rechecked your domain:

Now you have a complete setting with both domains (non-www and www) and two ip addresses, no mixed content warnings.

Perhaps add the last missing redirect

http + non-www -> https + non-www

@JuergenAuer

so it appears iptables is killing it so I just have to add the port for the ipv6 trace route?

Traceroute now finds your domain:

This is b/c I shutdown ip6tables. I would have to add the port for ICMP for ipv6 then correct?
