I can access deskMate desktops from home, but not from the corporate network. What is the reason?

Especially in companies, access to the Internet is often restricted by proxy servers and firewalls.

We have made the requirements for access to deskMate desktops as low as possible, but if access from the corporate network is not possible, please pass on the following requirements to the IT admin of your company.

The native software client will not work if a proxy is used which breaks the certificate chain for content/ssl inspection.
The native software client and the deskMate connection proxies communicate over a proprietary realtime protocol over TCP/443 which differs from HTTPS and must not be intercepted.

The web client uses a secure WebSocket connection (wss://) over TCP/443 to the deskMate connection proxies.
A company proxy must allow WebSockets and the HTTP protocol upgrade mechanism for this connection to work.

Following FQDNs/IPs could be whitelisted (TCP/443):

connproxy-1.deskmate-connection.com (185.14.48.150)
connproxy-2.deskmate-connection.com (185.14.48.151)
…
connproxy-15.deskmate-connection.com (185.14.48.164)
