In this case, the server may stop after switching from the trial version to the free version. To fix this issue, go to <strong>Summary \u2192 License info<\/strong> in the TrueConf Server control panel and click the <strong>Register<\/strong> button. Then <a href=\"https:\/\/trueconf.com\/docs\/server\/en\/admin\/registration\/\" target=\"_blank\" rel=\"noopener\">re-register the server<\/a> with your registration key (you can find it in the email that you received when first downloading TrueConf Server).<\/p>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">If TrueConf Server still doesn\u2019t launch, follow the next steps.<\/p>\r\n\r\n<h3 id=\"log\" class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">Step 2: Check Server Log<\/h3>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">Make sure that <a href=\"https:\/\/trueconf.com\/docs\/server\/en\/admin\/start-settings\/#server-log-files\" target=\"_blank\" rel=\"noopener\">your server log<\/a> contains no hardware key error string:<\/p>\r\n\r\n<pre class=\"lang:default decode:true wrap:true\">07\/02\/2017 18:54:08|0| 2354| UNKNOWN| CHECK CERT: HW key is failed!<\/pre>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">If it does, <a href=\"https:\/\/trueconf.com\/blog\/knowledge-base\/fix-check-cert-hw-key-failed-error\" target=\"_blank\" rel=\"noopener\">follow troubleshooting steps set out in our blog<\/a>.<\/p>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">This error could occur if you, for instance, moved your TrueConf Server to another computer or reinstalled Windows.<\/p>\r\n\r\n<h3 id=\"connection\" class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">Step 3: Check Internet Connection<\/h3>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">TrueConf Server Free, a free version of our video conferencing server, cannot launch without an Internet connection. Make sure that the computer with the server installed is connected to the Internet. To troubleshoot Internet connection problems, contact your network administrator.<\/p>\r\n\r\n<h3 id=\"license\" class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">Step 4: Check Server License Validity<\/h3>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">Check TrueConf Server license validity in the <a href=\"https:\/\/trueconf.ru\/docs\/server\/ru\/admin\/info\/\" target=\"_blank\" rel=\"noopener\">control panel<\/a> by navigating to <a href=\"https:\/\/trueconf.com\/docs\/server\/en\/admin\/info\/#about\" target=\"_blank\" rel=\"noopener\"><strong>Summary \u2192 License info \u2192 Registration details<\/strong> section<\/a>. If your license has expired, <a href=\"https:\/\/trueconf.com\/company\/contacts.html\" target=\"_blank\" rel=\"noopener\">contact us<\/a> for renewal.<\/p>\r\n\r\n<h2 id=\"register\" class=\"h4--main h4--thick black-text ui-mb-xs-3 ui-mt-md-1\">Problem 3: TrueConf Server Doesn\u2019t Register<\/h2>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">Make sure that the computer with TrueConf Server installed can access <code>reg.trueconf.com<\/code>, a registration server, over 4310 TCP port. This is mandatory if a free version is used.<\/p>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">You can check this, for instance, by using a telnet utility with the following command:<\/p>\r\n\r\n<pre class=\"lang:default decode:true wrap:true\">telnet reg.trueconf.com 4310<\/pre>\r\n\r\n<div class=\"accent-note accent-note--line accent-note--special ui-mb-sm-1 ui-mt-xs-3\"><p class=\"primary-medium-text\">\r\nFor running telnet command on Windows, please make sure that the Telnet Client is installed on your computer. Go to <strong>Start \u2192 Settings \u2192 Apps \u2192 Programs and Features \u2192 Turn Windows features on and off<\/strong> and check the <strong>Telnet Client<\/strong> box. \r\n<\/p><\/div>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">If the registration server cannot connect to your server, you will see the following message:<\/p>\r\n\r\n<pre class=\"lang:default decode:true wrap:true\">Connecting To reg.trueconf.com...Could not open connection to the host, on port 4310: Connect Failed.<\/pre>\r\n\r\n<p class=\"primary-medium-text ui-mb-sm-1 ui-mt-xs-3\">In this case, solve TrueConf Server registration problem by providing your computer and organization\u2019s network equipment with access to the above address and port.<\/p>\r\n\r\n","protected":false},"excerpt":{"rendered":"What to do if server does not start or can\u2019t register?
