All you can do is forwarding this message to the support of your provider.
This typically happens with cheap/free shared hosting packages and either too many clients on the same machine or some clients stressing the machine to its limits.

This message clearly shows that one of Ossn's database requests can't be answered in a reasonable timeframe because the server is obviously too busy with concurrently handling other requests.

Maybe your provider is able and willing to fix the situation or offers an upgrade to a more reliable service. If not, you should change to someone who is known to be capable of running community software without these nasty timeouts. See https://www.opensource-socialnetwork.org/hosting for some recommendations.

This is the error message I m getting

Please see:

With the error 500 you're getting there must be something meaningful in your webserver's log file.
If in doubt where this error log file is located, please consult your provider.
