quarantined email release fails

Hi Adrie,

No issue reported yet. Check in the smtp.log when you release the quarantined mail, do you see any errors? 

"Releasing has recently gone wrong on my macos Sierra machine." Did you mean that the emails are releasing perfectly through a Windows system?

Thanks

I wouldn't know, I do not have access to a windows PC. 

What I know is that, on the same macos machine, Firefox and Chrome are working.

Cheers. Adrie

That points to a problem with DNS  configuration.   How does your setup differ from DNS Best Practice?

Hi,

Well yes, that's what I meant by when I use the ip-address the release works fine. However I am quite sure this is not a dns issue while the http(s) request always reaches the proper server instantly, there is no dns request noticable (like eg. when root-servers are queried, because of no or bad forwarders are used)

The issue here has to do with misuse of https for a http request which I am not able to pin-point (aaargh)

Thanks anyway for helping.

Regards. Adrie 

Hello, 

Has a fix been found? We're having the same issue. Whenever our Chrome users click on the Release link on the Quarantine report, it will redirect the request from http to https, which results in the page not loading and the ERR_SSL_PROTOCOL_ERROR. 

Is there a way to make the Release link use https instead of http? 

Thanks!

Did you try a Google on stop chrome from redirecting to https?

Cheers - Bob

I haven't tried it yet. The thing is this is happening to all of our users who use Chrome on their personal PCs. They are so many I can't manually apply that Chrome fix to every one of them. 

I was looking for a fix on the UTM side of things, so that way the problem will be fixed for everyone. 

This suggestion is an experiment, and I give it a 10% chance of success.  In Webserver Protection, define a Real Server on "Internal (Address)" as HTTP (not HTTPS) using the port you've configured for the Quarantine Report.  Next, define Virtual Servers on "Internal (Address)" and "External (Address)" that use HTTPS on the same port.  Please report your results.

Cheers - Bob

Thanks for your suggestion! But, unfortunately, I don't have a WebServer Protection license so I can't access that feature. I only have a Network Protection and Email Protection license on my UTM.

Your reseller can get you a 30-day trial license for Full Guard so that you can test this.  Full Guard costs less than the combination of any three of the five subscriptions included.

Cheers - Bob

We have the same problem as described in the 1st post

attempting to release a quarantined mail item from the digest fails with

Safari can’t open the page “https://<fqdn>:3840/release.plc?proto=smtp&amp;cluster_id=0&amp;message_id=1ezWqw-0004mt-9G&amp;size=9707&amp;whitelist=0” because Safari can’t establish a secure connection to the server “<fqdn>”.

this is true of both Safari and Firefox on Mac 10.12.6

the link in the digest is

http://<fqdn>:3840/release.plc?proto=smtp&cluster_id=0&message_id=1ezWqw-0004mt-9G&size=9707&whitelist=0

NB http

our device is UTM 9.508-10

I think it is a DNS michmash rather than browser

I think it is a DNS michmash rather than browser

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

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:

---

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)

Gary

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) ?
