Problem/Bug Can't join my server

So, Everytime I join my server it says Java.net.ConnectException: connection refused: no further information.
I have Pretty big playerbase and everyone can join but me and like 3 other people but everyone else can join. I tried restarting the server and looking on the internet and stuff but mostly all of them are from a local host. This server is hosted by a company which I used for over 1+ years and I never had this Problem, If someone could Please help me and thanks!

Can you join other servers?

 

Click 'direct contact' then type localhost or try using your IPv4 adress which you can find doing these steps

1. >> Go into the windows icon search and type cmd

2. >> In the cmd ( Black box ) type ipconfig

3. >> Find your IPv4 adress

4. >> In minecraft click add server then type in your IPv4 Adress

Hope this helped!
