 @PhilipDAth Thanks for response.   Sorry for the late update on this thread. The issue turned out to be one of the intermediate certificates was not issued by Global CA. So we created the entire chain of certificates again with proper Global CA and it resolved the issue.   Suggestions: 1. Ensure certificates are issued by Global CA. 2. If there are multiple chain of certificates then present all chain of certificates until root (server certificates + Intermediate certificates + root certificates) while connecting to Meraki.   ...

We are integrating meraki with another application which acts as web server. SSL certificate configured in application webserver. Certificated has been signed and issued by authorized CA    1. Webhook configured towards application webserver in Meraki  2. When we click "send test webhooks" from Meraki GUI it shows "failed" whereas in application server side below error reported,   Traceback (most recent call last): File "/usr/lib64/python2.7/SocketServer.py", line 295, in _handle_request_noblock self.process_request(request, client_address) File "/usr/lib64/python2.7/SocketServer.py", line 321, in process_request self.finish_request(request, client_address) File "/usr/lib64/python2.7/SocketServer.py", line 334, in finish_request self.RequestHandlerClass(request, client_address, self) File "/usr/lib64/python2.7/SocketServer.py", line 649, in __init__ self.handle() File "/usr/lib64/python2.7/BaseHTTPServer.py", line 340, in handle self.handle_one_request() File "/usr/lib64/python2.7/BaseHTTPServer.py", line 310, in handle_one_request self.raw_requestline = self.rfile.readline(65537) File "/usr/lib64/python2.7/socket.py", line 476, in readline data = self._sock.recv(self._rbufsize) Error: [('SSL routines', 'ssl3_read_bytes', 'sslv3 alert certificate unknown'), ('SSL routines', 'ssl23_read', 'ssl handshake failure')]   3. TCPDUMP shows Meraki responds backs "Certificate Unknown (46)" for "Server Hello, Certificate, Server Hello Done".   Questions, 1. How Meraki differentiates Known and unknown certificates? 2. Do we need add webserver certificates in Meraki? ... View more
