quarantined email release fails

Releasing has recently gone wrong on my macos Sierra machine.

Tried it with Safari, Firefox and Chrome but all fail:

Safari:
Safari Can't Open the Page "https://<fqdn>:3840/release.plc?proto=smtp&mp;cluster_id=0&amp;message_id=1c2X06-0006pM-MV&amp;size=3469&amp;whitelist;0" because Safari can't establish a secure connection to the server "<fqdn>".

Firefox:
Secure Connection Failed
An error occurred during a connection to vgk.rcan.nl:3840. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

 

Chrome:
This site can’t provide a secure connection
<fqdn> sent an invalid response
Try running Network Diagnostics.
ERR_SSL_PROTOCOL_ERROR

 

Update:

Now, a day later I found out that Safari is redirecting the http://<fqdn>:3840 to a https request. Odd. anyone experiencing similar issue?

  • The browser reports an SSL error

  • from your PC can you ping utm.hiddendomain.com please? What is the result?

  • Yes we can ping the fqdn from both internal and external utm interfaces, both return the same, correct IP. There is no problem with the DNS.

    On clicking the release link utm http daemon log has this

    2018:03:27-12:19:36 utm httpd: 192.168.2.157 - - [27/Mar/2018:12:19:36 +0100] "\x16\x03\x01" 404 -
    2018:03:27-12:19:36 utm httpd: 192.168.2.157 - - [27/Mar/2018:12:19:36 +0100] "\x16\x03\x01" 404 -
     
     
  • Probably I know the answer.

    Now:
    Define a host

    Name:  utm
    Type:   Host 
    Ip4 Address: 192.168.2.1 (your internal interface IP) 
    DHCP: No DHCP Server
    DNS Settings: utm.hidden-domain.com (your FQDN that is equal in Quarantine Configuration Hostname) 

    Flush Dns in PC, Ping it and release the email

  • I said from your PC, not UTM

  • testing the fqdn with openssl

    prosserg@ITRoom-Mint ~ $ openssl s_client -connect utm.<fqdn>:3840
    CONNECTED(00000003)
    140409629832864:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:795:
    ---
    no peer certificate available
    ---
    No client certificate CA names sent

    SSL handshake has read 7 bytes and written 295 bytes
    ---
    New, (NONE), Cipher is (NONE)
    Secure Renegotiation IS NOT supported
    Compression: NONE
    Expansion: NONE

    The utm has no virtual server configured for SSL on port 3840, yet the utm is causing the browser (I'm now using Firefox on Linux) to switch from http to https

    BUT as previously noted, the same release link works fine on an iPhone (Safari)

  • Of course that is what I was doing and reporting, from a PC inside the network and from a PC outside the network. I was confirming that DNS is correct.

  • Thanks for the tip, but...

    Please explain what you mean by "Probably I know the answer." What IS the problem and why is this an answer ?

    Gary

  • Test the Host configuration as I said before.
    You are entering in loopback. And you didnt mentioned your IPHONE Connection 3G or wifi

    If You are from outside you can release the email from your external IP, from inside from your internal
    Hope you are clear on tha

  • Oldeda

    iPhone works fine on wifi and on 3G

    utm httpd: 192.168.15.138 - - [27/Mar/2018:13:24:26 +0100] "GET /release.plc? <----internal device

    utm httpd: 85.255.237.84 - - [27/Mar/2018:13:25:19 +0100] "GET /release.plc? <----external device

    You say 'you are entering in loopback' - I appreciate you are trying to help, but that phrase doesn't make sense to me. 

    You say test this configuration

    Name:  utm
    Type:   Host 
    Ip4 Address: 192.168.2.1 (your internal interface IP) 
    DHCP: No DHCP Server
    DNS Settings: utm.hidden-domain.com (your FQDN that is equal in Quarantine Configuration Hostname)

    so what definition do you propose for my other internal networks (5 in total) ?
