RAD Server Installation Windows

[ajoe]

Hi, I am quite new here. Sorry, I do not know German, and I have been using google translate to go through the posts here, as I am stuck with some of the issues that were discussed here.
I am using Delphi 10.4.2 and trying to host the console and the application on IIS 10.
I could host the application correctly, but I have issues with the console which is hosted in IIS. The hosting of console went fine, I can login, see the pages, and all looks good. But, when I click on Logout, the Logout doesnt happen. It remains in the same page, no error message shown. In firefox 88.0, debug tools, "Konsole" I could see the message :

GET http://192.168.110.153:30302/EMSCons...ServerMethods/
[HTTP/1.1 500 Internal Server Error 16ms]

under the above error in "Antwort" it says
JSON
error : "invalid request format. /classname/methodname and eventual parameters expected"


I have attached the log file from IIS which is created when the Logout is clicked, and also the screenshot of devtools from microsoft edge.

I would really appreaciate if someone could help me to identify the problem.
Thanks in advance.
