    Good morning,

    I'm operating a server via Team Viewer, and I'm installing a software that imports data from another server, both at the same network, using a HTTPS browser, but, a "It's not possible to access that site" appears everytime. I'm able to ping the server I'm trying to reach, but when I telnet it via cmd prompt, I receive the message "Could not open a connection to host on port 443 : Connect failed". How can I grant the access that server?

    Isn't the default telnet port = 23 ?

    Yes, it most certainly is. However, as you know, it can be configured to use any port by adding the port number at the end of the command line.

    For the @Andre.Amancio . Did you open the default HTTPS port, which is 443? Also, if there's a website running on the servers). How are those configured? If you're using IIS? Do you have the correct bindings set?
