Hi Tomomi,

I'm also running IdP 3.4.4 on CentOS (7.6), although with Jetty and
not tomcat/apache.

Have you given the server a DNS name, and certificates?
You should be able to check the status then like on my test server below:

Let's see if that works first of all.

Are you trying to do IdP-initiated SSO first, then SP-initiated IdP?
Usually the latter is normal (IdP metadata must be uploaded to this
test SP [or in general, to somewhere the SP can read it from]).
If you already created metadata for the IdP (assuming you have a DNS
name), could you upload it to the SP successfully?

Just a guess, if it is a Java exception nothing ever gets to the point
where logs will be written.
Please check you have set up the Idp properly so that you can see the
status details like on my example above.

Also, I see there are some limitations of the test site you are trying to use.
Please check that you are not trying to use signed AuthNRequests or
trying to receive encrypted SAML assertions:

Probably need to verify your IdP is really set up completely first.
