Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .

You need an "External Dedicated Permanent IP Address".

Usually, the provider purchases 0.5–1 $ per month.

Or take, as advised above, a virtual server.

Or try services like no-ip.com

    In order for your messenger to work through the Internet, it must be placed on some server hosted on the network, for example, by renting a virtual hosting service. The server will need to be raised with the address 0.0.0.0, which will allow you to connect to it via any network interface available on the hosting. Accordingly, the server address will need to enter in the client.
