If you are encountering connection issues with TQ then I’m afraid the network diagnostics in the launcher are not going to help you. It only test your connection to the update servers it does not do any tests for TQ.

If your ISP is not able to assist you with your issue you can file a ticket wit customer support and I can try to help you figure out what’s causing it.

But it’s very likely the issue is originating somewhere outside our network and yours, most likely somewhere in the connection path from your ISP to the server. Most connection issues these days appear be somewhere in the connection route from the user to the server.
