Well, basiclly I was playing on a SAMP server, then suddently I reconnected. When I wanted to join again, it appears like the server is offline, but the server is online. What should I do to fix this?

Contact the server owners maybe?

I did. Server is working perfectly for everybody else except me.

Maybe its a internet issue (try to reboot router)
or
If its SAMP issue reinstalling SA-MP again.
