<p>If our authentication service is temporary not available, you receive the following error message:<br /><br /><img src="/Media/files/filemanager/images/global_authentification_service.PNG" alt="" width="345" height="184" /></p>
<p>If you receive the error message for a longer time or the error message appears although another computer is online, you should check the following steps:</p>
<ol>
<li>Please check your Internet connection first.</li>
<li>If an Internet connection exists, check your firewall settings or if an Anti-virus software blocks SYNCING.NET. Try to find out and deactivate this program temporary or allow SYNCING.NET to pass. Please allow the following IP addresses access to the Internet: <br /><br />IP: 92.205.232.131<br /><br />In addition, please allow the executable files SyncService.exe, SyncingOLWatchService.exe and NotificationService.exe access to the firewall settings.</li>
<li>If you are using a Hardware-Router, it’s possible that some Port are blocked. SYNCING.NET is using the TCP/IP Ports 443 and 55556 (you can also change the port via SYNCING.NET -> Configuration ->Options -> Account) .</li>
<li>If everything seems to be okay, you can check the connection to our server:<ol>
<li>Click Start -> Run…, enter “cmd” and click “OK”.</li>
<li>Type in “ping snt-app0.asbyte.com” and click Enter. Now the following text should be displayed:<br /><br />Pinging snt-app0.asbyte.com [92.205.232.131] with 32 bytes of data: <br /><br />Reply from 92.205.232.131: bytes=32 time=101ms TTL=128<br />Reply from 92.205.232.131: bytes=32 time=90ms TTL=128<br />Reply from 92.205.232.131: bytes=32 time=94ms TTL=128<br />Reply from 92.205.232.131: bytes=32 time=85ms TTL=128 <br /><br />Ping statistics for 92.205.232.131:<br />Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),<br />Approximate round trip times in milli-seconds: Minimum = 85ms, Maximum = 101ms, Average = 92ms</li>
</ol></li>
</ol>
<p>If this doesn’t help please install SYNCING.NET again. Download <a href="/en/download">SYNCING.NET</a> and install it over your existing version. All settings, "Sync Folders" or "Outlook Groups" and license keys will be retained. Then please check point 2 again.</p>
