CmWAN License used in Company or School

Last change: Dec 6, 2024

If you want to use a CmWAN license at school, in an institute or a company please check that your IT department allows the SSL connection to our CmWAN server. Specifically, this relates to HTTPS (Port 443 / TCP) to the host "cmwan.keller-cloud.com".

If you enter ID and password when starting SYMplus and this connection cannot be established the same dialog box will appear again after a few seconds.

It may be necessary to allow access to "http://r11.o.lencr.org" and "http://r11.i.lencr.org/". These URLs may be needed to verify the SSL certificate of the host "cmwan.keller-cloud.com".

If you are using a proxy, this article may also help: Setup a Proxy for CmWAN licenses

If the SSL connection is available but the software still cannot be started please create a logfile and send it to support@cnc-keller.de.
