Check your php error logs, they hold the key to your issues. Market connectivity is working fine, otherwise many would report problems. Also, your admin side being slow is not normal. It is probably caused by this timeout.
...and tried to install osclass in different server
What does this mean? Different hosting company? Localhost? Where do you host your files? What is your php configuration like? Check with line:
<?php phpinfo(); ?>
inside some empty file and access it directly from your website/server, post results here. If you get blank page, go to cpanel of your host and look for php section there, you'll find the command/link.

thanks everyone.
dev101, I tried fresh install on different hosts, or on different domain on the same host, it made no difference. Sites are working ok, and I can install plugins via ftp and then install them in plugin manager BUT I cannot connect to the market via the osclass backend.
I have no errors on the log (checking on cpanel) and as I mentioned earlier, in this server (in this host) , my install of osclass was connecting fine to the market some times ago, and i have installed several plugins through the backend with no problems in the past.
things has changed, i believe, since updating to 3.5.7.
phpinfo is too big to post here, i exceed the max leght of post allowed.
However, i can give you access privately to a osclass fresh install in this host, where I manually just installed phpinfo plugin.
thanks in advace for any advice.
