Hi !

Show site 3 on internet ok, but on local net shows site 2.
I have a self hosted server in the local-net and I log in to it with (ssh addressees) The server is 2 cores 3 GHz possessor with 2 GB ram. I have Ubuntu 18.04.3 on the Server and my laptop is a 4 Core AMD possessor with 8 GB ram. And Ubuntu 18.04 desktop. I have Fiber on Internet so it is 100 Mb S speed up and down. On the server it is 8 web sites in Ubuntu Apache and they all have certificate from cert-bot on all sites. All site show up on internet, but It is one side s site 3 that are normal on internet but locally when i open it shows side 2,
to show right I have to open with WP-admin and then show side, then it ok. I do not understand this.
The host file i correct to . Anybody had this problem.
To tainting the security I hope then somebody can give mi advice.

Possibly because the apache server is providing you with sites according to url you are using to get there? So from inside your browser says https://myserver but your external DNS means you have to go https://mysite.myisp.com
