    Hello, I ran the automated Perfect Server script for a new server, using Ubuntu 24, on a VPS from OVH. Apparently, all went well and for a couple of days it was it seemed operational. I suspect that Automated Upgrades destroyed something, but have been unable to find the cause/resolve it. I attempted an ISP Config update, which ran successfully, and I can reach the site for my server, but not through the FQDN, so Apache seems to be working.

    I'd like your advice, is there worth in troubleshooting? Or, should I re-do the server install? Either way I'd like your opinion on what may have happened to avoid the same mistake. Please let me know any questions/instructions.

    Note: I used Certbot on purpose since I'd need to move websites that use it once the new server is all good.

    First, you seem to have an issue with Postfix. Try to start postfix and if it does not start, check the mail.log to see why this happens.

    Regarding ISPConfig, it is listening on port 8080, and the local firewall port 8080 is open, so you should be able to reach it. Try accessing it using the server's IP address instead of its hostname. Perhaps you have a DNS issue where the hostname no longer exists or points to the incorrect system.

    It ended up being a permissions issue, I chose to re-install, so I'm back on the road. Thanks!
