So I am hosting my server from McPROHosting and I can't add it query is enabled and I am entering the right query, it is online and everything is okay but I can add it

Here are a handful of ideas for you:

1. You confirmed your server is up-to-date.
2. You confirmed your server is not running any query plugins, like minequery.
3. The query port is correct.
4. You've opened the query port in any network software (firewall, router) for TCP/UDP.
5. You've setup your server.properties/.
6. You've tried without mods that are known to break the server query, namely MCPC+ and bungeecord.
7. You've confirmed you are not blocking GT:

208.167.241.190
208.167.241.185
208.167.241.186
208.167.241.183
208.167.241.189
108.61.78.147
108.61.78.148
108.61.78.149
108.61.78.150

Everything is ok, but for some reason I can't add it
