Resolved Host error after update to 18.0.72

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

18.0.72

Hi all,

After the upgrade to 18.0.72 I'm encountering the following problem:
My laravel application expects a certain domain to verify if it's routes need to pass to the first or second website. This worked like a charm after the update.

After the update, I get a "default-xxxxx" host instead of the actual domain from Plesk:
HTTP_HOST: default-82-165-51-122 - Host ($request->getHost()): default-82-165-51-122

Expected:
HTTP_HOST: hp.example.com - Host ($request->getHost()): hp.example.com

Now I have unmatched routes, so my application isn't working anymore.

Does anybody know a fix for this matter?

Is the domain in question assigned as the default for the IP address?

Yes it is. Everything worked perfectly before the latest Plesk Obsidian update. I think it has something to do with Nginx reverse proxy.

Yeah, I thought so...

Issue - 18.0.72 broke IP Default Webites Ubuntu 24

I've had to switch my sites (2 different Ubuntu 24 servers) to SNI...I set the default site for the IP address to none, until the issues has been resolved.
Can you look into this please @Sebahat.hadzhi? Thanks again.

@MaasRick , could you please confirm if you have the affected domain set as Default Site in Tools & Settings > IP Addresses?

This also happened on my Ubuntu 24 Server. I also changed my Default Site to None to fix the issue

Hi @Sebahat.hadzhi Some more information for you, I just tested my site (that was set as default for the IP) at SSL Labs and it still shows as the default, so there's no notice that the site is SNI which is what I was expecting.

FWIW - Issue - 18.0.72 broke IP Default Webites Ubuntu 24

The behavior was identified as a bug with ID PPPM-15085. The fix will be introduced at one of the upcoming releases. In the meantime, the only workaround is setting Default Site to none in Tools & Settings > IP Addresses.

Confirmed, affected domain is set as default (I only have domain, and an alias)

Affirmative, this fixes the issue. If you keep the website as default website, and turn nginx proxy mode off, it also works. This was my previous workaround. Now I have turned nginx's proxy mode back on, and set the default domain to none and it works.

The issue has been resolved after Plesk Obsidian 18.0.72 Update 2
