Edit:re-instaling Sa-mp won't to work before you suggest too
Delete all the servers, close samp, open it, open the servers again. If not you didnt locate thr samp client good when installing. It has to be in the gta san andreas map.
Sometimes if the server owner doesn't want you on their server, they do have the choice to completely firewall you or your IP, which could be the reason why it hasn't appeared.
