I am trying to set up IPSec Remote Access Dialup User VPN with FortiGate 6.4 trial VM downloaded from Fortinet website. I am trying to make it work with FortiClient 6.0.5. I have done the configurations as per guides and followed some youtube videos for understanding of IPSec as well. I have made sure that my phase 1 and phase 2 configurations on both ends are same. I have two NICs attached to the VM, one assumed to be the local network which needs to be accessed by the clients after VPN tunnel gets established (192.168.137.0/24), and the other assumed to be WAN network which would be accessed by the clients to establish VPN (192.168.10.0/24). The system on which Fortinet client resides is also part of the WAN network (192.168.10.0/24).
I am unable to make the configurations work and stuck. On FortiClient, I get the following error:
"VPN connection failed. Please check your configuration, network connection and pre-shared key then retry you connection. If the problem persists, contact your network administrator for help."
On FortiGate CLI, I get the following logs with debugging enabled:

As it says gw validation failed, which gateway is referenced here? Any hint on what could be the issue in the configuration would be appreciated..
Waiting for kind response
This error is related to EAP it seems, try the following in the configuration of your tunnel on the FortiGate:
config vpn ipsec phase1-interface
edit IPSECVPN (this is the name of your tunnel)
set eap enable
set eap-identity send-request
set authusrgrp 'the group your user is in'
next
end
Otherwise, if you don't mind, switch to IKEv1 to mitigate this, that will make things in general probably slightly easier.

Using "Azure Relay Hybrid Connection" while sending and receiving messages using the websocket protocol, if there is delay in receiving the response no exception occurred.
But when sending and receiving messages to "Azure Relay Hybrid Connection" using HTTP protocol and if there is more than 60secs delay in receiving the response, error response received which says 504 Gateway Time-out exception & exception message says "The request was routed to the listener but the listener did not respond in the required time', Why??
Since it is HTTP protocol, it can't be keep the connection open forever like websocket?
In "Azure Relay Hybrid Connection" while using HTTP protocol, by default 'Gateway Time-out' is 60secs, how to extend the default timeout duration?
Timed-out requests can be retried?
I have a HiveMq mqtt broker credential to connect MQTT broker using PubsubClient from Ardurno .. I tried to connect its throwing an error -4 time out.
Hivemq broker url - xxxxxxx.s2.eu.hivemq.cloud
Username : xxxx
Password : xxxx
Port - 8883
No Certificate
Code - client.connect("client_id",mqtt_username,mqtt_password))
I tried in MQTT explorer its connected because i enabled the Tls option.Attached the screen for your reference. Could some one share the code to enable the Tls on PubsubClient.(Sample code). Note that no certificate. only encription.(Hive does not give certificate)

I want to implement Azure Service Bus Topic/Subscription. Something like this
I'm looking at the Python implementation in the Azure Docs. What I don't understand, is when the message is sent, how does it know which subscription to go to?
def send_single_message(sender):
# create a Service Bus message
message = ServiceBusMessage("Single Message")
# send the message to the topic
sender.send_messages(message)
print("Sent a single message")
# create a Service Bus client using the connection string
servicebus_client = ServiceBusClient.from_connection_string(conn_str=CONNECTION_STR, logging_enable=True)
with servicebus_client:
# get a Topic Sender object to send messages to the topic
sender = servicebus_client.get_topic_sender(topic_name=TOPIC_NAME)
with sender:
# send one message
send_single_message(sender)
print("Done sending messages")
print("-----------------------")
What I don't understand, is when the message is sent, how does it know
which subscription to go to?
This is accomplished through topic filters. Each message that gets sent to a Topic is "kind of broadcasted" (for the lack of better term) to every Subscription and the Subscription only accepts a message when that message matches one of the filter rules specified for that Subscription.
You can learn more about it here: https://learn.microsoft.com/en-us/azure/service-bus-messaging/topic-filters.
Trying to create a webhook subscription to an Event Grid topic fails with an error reported in the Azure portal:
Deployment has failed with the following error..."Webhook validation handshake failed for https://xxx.xxx.xxx.xxx:10443/event. Http POST request failed with response code Unknown
My webhook is a .NET core test app using a Kestrel server. I can see from logging that there is an incoming connection from Azure when I try to create the subscription, but this is immediately followed by a disconnect.
Microsoft.AspNetCore.Server.Kestrel: Debug: Connection id "0HMCE876DPTD6" accepted.
Microsoft.AspNetCore.Server.Kestrel: Debug: Connection id "0HMCE876DPTD6" started.
Microsoft.AspNetCore.Server.Kestrel.Transport.Sockets: Debug: Connection id "0HMCE876DPTD6" received FIN.
Microsoft.AspNetCore.Server.Kestrel.Transport.Sockets: Debug: Connection id "0HMCE876DPTD6" sending FIN because: "The client closed the connection."
Microsoft.AspNetCore.Server.Kestrel: Debug: Connection id "0HMCE876DPTD6" disconnecting.
Microsoft.AspNetCore.Server.Kestrel: Debug: Connection id "0HMCE876DPTD6" stopped.
It appears that there is an error during the TLS handshake. Are there any specific requirements for TLS for the webhook. I'm using the default certificate ("ASP.NET Core HTTPS development certificate"). This won't be trusted by Azure - is that a problem?
As per the documentation Using self-signed certificates for validation isn't supported. You need to use a signed certificate from a commercial certificate authority (CA) instead. You can also go through this troubleshooting document if it helps.
We have SignalR service hosted on Azure.
For technical reasons, it is essential for us to maintain as stable connection between client and host as possible. And what is happening is that at relatively random intervals some clients got disconnected. We know that this is not related to internet connectivity on the clients's side.
So, the question is, how we can determine reason of a disconnect.
Our SignalR hub implements overrides 'OnDisconnectedAsync'. And this method has 'Exception exc' parameter. Unfortunately every time it get's triggered, exc is always null (I was hoping to find details for disconnect there).
Additional details:
We user following SignalR packages on Server side:
Microsoft.AspNet.SignalR (2.4.0)
Microsoft.Azure.SignalR (1.0.5)
On client side we use "Microsoft.AspNetCore.SignalR.Client.Core" (1.1.0)
Also, we checked and we have enough resources on Azure SignalR (units)
Here are logs when user gets disconnected (happen after OnDisconnectedAsync):
2020-03-15 11:38:07.391 +00:00 [Debug] Microsoft.AspNetCore.SignalR.HubConnectionHandler: OnConnectedAsync ending.

When the client is connected to the Azure SignalR, the persistent connection between the client and Azure SignalR can sometimes drop for different reasons. This section describes several possibilities causing such connection drop and provides some guidance on how to identify the root cause.
Possible errors seen from the client-side:
The remote party closed the WebSocket connection without completing the close handshake
Service timeout. 30.00ms elapsed without receiving a message from service.
{"type":7,"error":"Connection closed with an error."}
{"type":7,"error":"Internal server error."}
Root cause:
Client connections can drop under various circumstances:
When Hub throws exceptions with the incoming request.
When the server connection the client routed to drops, see below section for details on server connection drops.
When a network connectivity issue happens between client and SignalR Service.
When SignalR Service has some internal errors like instance restart, failover, deployment, and so on.
