Hello experts,

I have a problem with connecting the OZW772 with the Remote Tool Access program.RTA is giving me a message that says - Unable to connect to site.The server is restarted by web and manually with unpluging the power supply.

Does anoyne have the same issue with this kind of server?

Regards,

Stefan

We have same problem! Nobody cam connect with RTA. 
It is frustrating!

I have the same problem :(

What is your Windows version? Recently, Win11 has had issues with localhost, and the OZW IP address is localhost 127.0.0.2. Maybe it is connected with this problem?

I've personally tried several PCs with updated Win11, non-updated Win11, and Win10. I always get the same error.

Could this be because the certificate for the domain "clx.connectivity.ccl-siemens.com" expired on October 8, 2025?

OK, I can confirm that the problem is the expired Siemens domain certificate.
If you set the PC's date to a date before October 8, 2025, it should work again.

Any news? How to solve this problem? There is a fix or something?

it's all right, I set the PC's date to october 1,2025 and it work
