Could not detected compatible server

ownCloud 5.2.1.13040 979bb9
Libraries Qt 6.4.3, OpenSSL 3.1.2 1 Aug 2023
Using virtual files plugin: wincfapi
OS: windows-10.0.22621
QPA: windows

Server is in Virtualbox and im not sure how to check information about it.
I can only log in thanks to the server URL, other methods do not work (highlighted in gray).
Every time you try to log in to the address (example)
http:// 193.238.1.327/ I get the error “Could not detect compatible server at “http:// 193.238.1.327/”. Before this, a message also pops up that the connection is not secure and asks me to confirm the login.
I tried to search on the forums, but I just started working with owncloud and in didn’t help. I don’t quite understand how to solve the error.
However, when I try to enter “https:// 193.238.1.327/” I get the error “TLC Certificate Error”:
The host name did not match any of the valid hosts for this certificate

Most likely I need to configure certificates, but can someone explain how to do this?
If this is not the problem, then what should be done?
