Neil Kleinfeld 0 Posted September 26, 2016 Share Posted September 26, 2016 I just installed the latest (1.8.3) on a Mac running MacOS Sierra (ver 10.12) as the client and on a PC running Windows 10 (latest version) running as the server and also have now have error trying to connect. Worked fine with last version before this one. Server does not seem to see client and client is timing out over and over again. Â I have restarted both the MAc and PC and same errors occur. Help?

Hilario Ortigosa Monteoliv 0 Posted September 26, 2016 Share Posted September 26, 2016 I've had to reconfigure Mac server (10.11.x) from scratch, and I have had the same timeout issue (Linux client, both updated). I've solved it by disabling SSL encryption on both sides, temporary Link to post Share on other sites
Sean Kerns 0 Posted September 26, 2016 Share Posted September 26, 2016 It's not just me, then. I upgraded two Mac clients - client on El Cap, and server on Sierra, to 1.8.3, and they jabbered back and forth about each other, but wouldn't connect. I dropped back to 1.8.2, and they worked again. I'll try disabling SSL as mentioned below, and see if that does it. Link to post Share on other sites

Larry Bushey 0 Posted September 26, 2016 Share Posted September 26, 2016 Disabling SSL works... Â I can confirm that disabling SSL works. I am using Ubuntu-MATE 16.04 as my server and MacOSX 10.11.6 as the client. Link to post Share on other sites
Andrea M Olivier 0 Posted September 26, 2016 Share Posted September 26, 2016 I'm having the same problem. Mac 10.11.6 server, Windows 7 client. If I turned off SSL, I can get it to work. Link to post Share on other sites

Roberto Paolinelli 0 Posted September 26, 2016 Author Share Posted September 26, 2016 Disabling SSL works...  (yes)  Thank you very much indeed Mark  Best Regards Link to post Share on other sites
Micro 0 Posted September 26, 2016 Share Posted September 26, 2016 Disabling SSL alone did not fix it for me using MacSierra as my server. I had to delete the Synergy folder in ~/Library/ Synergy folder. Â After disabling SSL now on both sides I'm connected. Link to post Share on other sites
Lucas Croce 0 Posted September 26, 2016 Share Posted September 26, 2016 I'm not using Synergy Pro so it can't be SSL for me. Rolling back to 1.8.2 Link to post Share on other sites
Jonathan Nagle 0 Posted September 26, 2016 Share Posted September 26, 2016 It seems previous updates did not required re-registration. My Server machine reset its configs on applying this update, and forced me to re-register it (using Serial or login). When that happened, it generated a new SSL fingerprint. Â My client did not re-register, and was still using the old config with the old SSL fingerprint. This is why the server did not accept the SSL connection. Â The fix is to run through the config wizard again to re-register on the machine which did not force you to re-config (in my case, the client). Once that happens, it will ask you to trust the new SSL fingerprint and it should work. Link to post Share on other sites
Robert Berry 0 Posted September 26, 2016 Share Posted September 26, 2016 Windows (server) and Centos (client) here.  Same issue and fix ... on upgrade they wouldn't talk over SSL... re-ran the config wizard and put in my pro serial number in both. Everything works as expected now.  Robert   It seems previous updates did not required re-registration.

Derrik Pates 0 Posted September 26, 2016 Share Posted September 26, 2016 Same problem, using Linux Mint 17.3 on the server and MacOS 10.11 (El Capitan) on the client. 1.8.2 was fine, 1.8.3 turbo-hates SSL now. What gives? I've turned off SSL for now, since it's on my home network, but I'd feel better if it were on... Â Edit: Reran the wizard on my Linux Mint 17.3 desktop, and now it connects via SSL. This should be in big flashing red letters on the website. Link to post Share on other sites
sascha224 0 Posted September 26, 2016 Share Posted September 26, 2016 Same here, no connection to server (both client and server on Win10 x64). But for me, SSL is not available, getting the entry "NOTE: crypto disabled because of ns plugin not available". Executing the wizard or cleaning the config didn't fix it. Notified this error in RC and reported this to developers, but it isn't yet fixed in final. Have to stick with 1.8.2. Link to post Share on other sites
Ajitpal Virdi 0 Posted September 26, 2016 Share Posted September 26, 2016 I had the same issue. Win 8.1 64-bit - Server Ubuntu 14.04 64-bit - Client  I ran the Wizard on both: File -> Run Wizard  This fixed the issue. On the Client, I had to select "Accept certificate" or something like that after the Wizard finished. Link to post Share on other sites
Douglas Mueller 0 Posted September 26, 2016 Share Posted September 26, 2016 Same thing here. MacOS Sierra (client) Ubuntu 16.04 (Server). Â Everything was working in 1.8.2 Â Confirmed that re-running the wizard and accepting the SSL Cert on the client fixed the issue. Link to post Share on other sites
Leonardo Clavel 0 Posted September 26, 2016 Share Posted September 26, 2016 Same error here. Tried everything for over an hour. Then switched off SSL on both client and server and instantly fixed issue. Link to post Share on other sites
Steve Bigham 0 Posted September 26, 2016 Share Posted September 26, 2016 Hey all, Â I had the connection problems once I updated to 1.8.3. Read the email that went out from Synergy that said there was an issue and I would have to run the setup Wizard again. Tried this... didn't work. I tried to disable the SSL... Didn't work. many restarts and firewall adjustments to try and get it to work, No luck. Â MY FIX --> I uninstalled Synergy from the "server" computer and ran Revo to get rid of all the leftovers. Reinstalled Synergy and ran setup (the setup auto prompted upon installation). WORKED! Â Hope this helps some of you. Link to post Share on other sites
Larry Bushey 0 Posted September 26, 2016 Share Posted September 26, 2016 RESOLVED! Received these instructions by email from the Synergy team. They resolved the issue for me.  There's a known issue in Synergy 1.8.3 where the SSL plugin can be out of date, which stops the client connecting to the server. To fix this, please re-run the wizard on all of your machines. 1. Open Synergy on the server 2. If Windows: Go to the Edit, then click Settings 3. If macOS: Go to Synergy, then click Preferences 4. Ensure the "Use SSL encryption" checkbox is enabled 5. Go to File, then Run Wizard 6. Click Next until you see the Activation screen 7. Enter your login details or serial key 8. Click "Continue" and finish the wizard 9. Repeat those steps for each client  I'm sorry you had to do that, it's a pretty major screw up on our part, sadly we didn't see this while testing. If those steps don't help, please let us know so we can troubleshoot further. Thanks for your patience! Link to post Share on other sites
Robert Wall 0 Posted September 26, 2016 Share Posted September 26, 2016 Didn't work for me. On my MacBook, it seemed to (the MacBook is the server). On my Windows 10 client, rerunning the setup wizard didn't clear out the server cert fingerprint. In fact, uninstalling and reinstalling Synergy on Windows didn't clean it out either. I tried to delete a directory that had fingerprints in it - that didn't help either. So far, no way to cause the Windows client to reprompt me to authorize the server cert.

Brad Smith 0 Posted September 26, 2016 Share Posted September 26, 2016 I tried taking off SSL support, updated things with the wizard several times. Nothing would allow me to connect two devices that were working on 1.8.2. As I needed to work today I backed off till I could spend more time on this problem. I'll keep monitoring here to see if a fix comes. Link to post Share on other sites
