Please provide more details.

My setup look like this:
I have a Azure relay in Azure and one configured Hybrid connection.
On-prem I have a HCM service connected to that relay.
I have verified the connectivity using a webservice in azure also connected to the relay.

Now I want to connect to the relay from my devbox using portBridge (or anything that will work), in order to connect to the onprem resources.

This is my client config

 <portBridgeAgent serviceBusNamespace="*********-relay.servicebus.windows.net/*****test-erp" serviceBusAccessRuleName="RootManageSharedAccessKey" serviceBusAccessRuleKey="*****************">
    <portMappings>
      <port localTcpPort="80" targetHost="******app23" remoteTcpPort="80">
        <firewallRules>
          <rule source="127.0.0.1"/>
          <rule sourceRangeBegin="10.0.0.0" sourceRangeEnd="10.255.255.255"/>
          <rule sourceRangeBegin="172.0.0.0" sourceRangeEnd="172.255.255.255"/>
          <rule sourceRangeBegin="192.0.0.0" sourceRangeEnd="192.255.255.255"/>
        </firewallRules>
      </port>
    </portMappings>
  </portBridgeAgent>

The client connects but when try to browse the onprem web server I get "ERR_EMPTY_RESPONSE"

the log looks like this:

I have tested different localTcpPort ports.
The hostname is also configured to point to 127.0.0.1 in the HOSTS file.

@jfggdl Anything else I can do to help troubleshooting?
