Hi, I have received your email, in licensing it is shown as activated and if you are not receiving this message again then problem has gone.

Hi Chris, are you having issues with this? Are you using any firewall/proxy software on your computer?
Thank you,
Paul.
Chris and Paul,
I just wanted to say that I saw this message again a couple of times last week. It seems to have gone away, but I thought it might help to know that Chris isn’t the only one.

Hi Ray, this message usually appears when users have proxy or firewall software on their computers that might be blocking the ability to connect to our licensing server or that might be blocking port 80.
eM Client has to be able to contact the licensing server at least once in 14 days.
Thank you for understanding,
Paul.
I just received the same message (unable to communicate for 10 days). I’ve had the produce for over 2 months, so don’t know why this is happening now, as I haven’t changed my firewall or any related settings. Can you walk me through what I need to do to ensure that eM Client can communicate with the server? I’m not a techie, so need clear instructions. Thanks.
Actually, I just went to Windows firewall and added eMClient as an app. If that’s all I needed to do, then no help needed.
Hi Allen,
I got yesterday the message of eM client saying that it was not able to connect to the license server. Never had that message before, so I guess it was just a ‘hickup’ (of my internet connection or the license server).
I received this same message today when I started eM Client after rebooting my machine for the first time in over a month. Is it possible that eM Client only performs this check when it first starts and if you leave it running for multiple weeks without restarting, that causes this error?
Here’s a screenshot. Notice the “Ended in Update” bit which seems even more confusing - if the last attempt ended in an update, then the last attempt WORKED didn’t it?
Once I clicked OK and went to “Check for Update…” in the “Help” menu, I received a message “There is no update available”. This leads me to believe there is no issue communicating with the update server, so something else must be going on? I also did not receive the “unable to contact” error again when I closed and re-opened eM Client.
I do not have any proxies on this machine and my browsers are not configured to use a proxy either.
Hi Kevin, we had a temporary server downtime, so you may have received this error messages on application startup. eM Client tries to contact the licensing server on application startup if no connection to the server was made in past 24 hours. Otherwise the application should check once in 24 hours if the application is running.
Sorry for the inconvenience, hope this helps,
Paul.
Hi eMclient, I always sit with the same problem. Seems like my proxy is blocking the connection to the update license server. Question is what exeption do I need to add the allow eMclient to contact the license server.
Port 80 and 443 is allowed as most programs utilized these ports as default .
If you need to setup a Proxy/Firewall exception for our licensing server, you have to setup the exception to allow connections to either http://licensing.emclient.com/ or Port 80.
Hope this helps,
Paul.
Hi Paul, thank you for the reply. I’ll give it a go and let you know.
I have the same problem!
I got this “emclient unable to contact the update server” and the aplication is only in OFFLINE mode from now on.
part of the network sockets logs here
I have the same antivirus from the begging
I can access the the http://licensing.emclient.com/ from browser when I go to check for update I get nothing… no errors, no messages…
please help me out
When you click on the link to licensing, you are going to an https page. https usually uses port 443 or even 8080, not port 80 as required by the licensing server. Maybe eM Client has it set differently though.
If you temporarily disable your antivirus and firewall, do you still get the error?
did not work… very sad that I can no longer use emclient 
What version of Windows are you using?
windows 10.
my error is a 404 so I dont understand why my client can not find the license server
No proxy or VPN?
If you are using a laptop, you could try when connected to a different network.
got it fixed… it was the nxfilter (dns filter) thank for answering.
is there a way to configure a proxy inside the application? it could help in many cases. thank you for this great product
