RPC Proxy can't be pinged._ A Web exception occurred because an HTTP 405 - MethodNotAllowed response was received from Unknown.
Response from server received: 401
Client is not authorized to ping RPC proxy
You receive this response if the RPC Ping Utility test failed. The PRC Ping Utility test may have failed if HTTP access is denied, if there are incorrect credentials on the –Pswitch, or if the user exits.
Let’s begin with the following article：
The error you mentioned above may be caused by that HTTP access is denied or credentials is incorrect on the –P switch.
Thus, let’s try the troubleshooting below:
1. check if enalbing Outlook Anywhere and install the RPC over HTTP component. Because external Outlook clients use Outlook Anywere connect to the Exchange server:
2. since it’s a self-signed certifictae in your environment, please check if you have installed the certificate on all outside clients.
Additionally, to narrow down the cause, we can use ExRCA to check Outlook Anywhere connectivity:

Kindly please help on this.................job may be gone on this issue. it is little but now big as giant.
Sorry for delay reply.
As far as I know, 405 errors often arise with the POST method. Thus, we can use Network Monitor to confirm it:
Alternatively, I’d like to confirm if there is any firewall or some other device blocking the method in your environment. And we can use a local computer to test it.
