WebGUI: 503 Service Not Available / Tenant runlevel stopped

[christoph_volkert]

Hello,

we have migrated our old APO to a new OS and updated to APO SCM 7.0 EHP 4 with Live Cache.

If i try to access the WebGUI, via http (port 8000) and as well via https (port 8001), i got a ""Application Server Error" HTML Error 

503 Service Not Available

Tenant runlevel stopped

To enable WebGUI i have set Parameters for Ports pointing to https/8001 and http/8000 and restarted the server. Access to that ports is fine.

Then i have followed that manual 

https://community.sap.com/t5/technology-blogs-by-members/how-to-configure-web-gui-for-sap/ba-p/13208...

Could someone point me to where the problem is coming from? What "Tenant" is the error message pointing to?

Thank you

On the search for the timeout problem i cleared the >ICM Trace-File, restarted the ICM and checked the Trace File.

There are peer SSL-Errors listed, even i had not tried to connect via Browser after the restart, so i gues that could be a problem of a internal communication?

Can someone explain me where that SSL-error is coming from?

You are using a self signed certificate. You need to import it on STRUST to the system be able to recognize it.

Nope, thast was my browser, After clearing the log and restarting the ICM AFTER i closed all browser trabs, that ssl errors are gone.

Beside the ssl error, which would probably not prevent me from accessing WebGUI via http, i found one problem that raises questions about another wrtongly configured port maybe?

OK, that problem with the Linux socket file is gone after i deleted it manually.

I#ll check that ssl error at other servers with wworking WebGUI. That errors show up there as well and did not limit the function of the WebGUI.
