Error 523 for just one of domain names

Dear community, please help me to understand while i am getting 523 error when using HTTP Proxy AND DNS.
I just served new cloud server, i have 5 domain names that must be hosted there. 4 of them are completely ok, but one of them gives 523 error. All domains are using HTTP Proxy and working good with this server. Only domain with (.se) give error. Apache VirtualHost setting are completely equal with different origin certs. Everything seems to be ok, when i am turning off HTTP Proxy, just SSL reminder that certs is self signed.

If you feel comfortable to reveal your IP address post a screenshot of your DNS settings.

Thanks for your reply,

This is working quite fine.

The second screenshot points to a completely different server.

The issue is accurately described by the error message. Your origin is not reachable. Your server is simply down or otherwise unreachable ->

Try , - it is working , - maps to new server. That is working quite good. IP address is same. Firewall is accepting only https.

Listen 443 https
<VirtualHost *:443>
DocumentRoot /var/www/html/se
SSLEngine on
SSLCertificateFile /etc/ssl/certs/se.crt
SSLCertificateKeyFile /etc/ssl/private/se.key

<VirtualHost *:443>
DocumentRoot /var/www/html/pl
SSLEngine on
SSLCertificateFile /etc/ssl/certs/pl.crt
SSLCertificateKeyFile /etc/ssl/private/pl.key

Set your SSL mode to “Full strict” in this case.

I changed back to Proxy HTTP and DNS , and getting still getting error

Did you change the SSL mode?

Sandro, i even didn’t know that i can change it. Many thanks to you!!!
