Resolved Can not embed my sites as iframes on other sites

[boosterfan]

Hello guys,

we switched to another server.

Now we have a problem. We have some sites that are embedded in other sites. All sites are on our server.

On the old server this was no problem. But now, all browsers say, that they are not allowed to embed the sites?

We just restored the sites and did no changes.... Now we have debian 10 and latest plesk obsidian.

Any idea?

EDIT: Can be marked as solved. There were no changes to the site, but new orders in nginx file. Now it works.
