Upgrade Network Yeilds error Your server may not be able to connect to sites running on it. Error me

After updating some plugins I went to update network link and got an error after waiting some time.

Warning! Problem updating http://bronxcounty.aresnyc.org. Your server may not be able to connect to sites running on it. Error message: Operation timed out after 120000 milliseconds with 0 bytes received

I repaired and optimized the database.
I also went to the Bronxcounty website and all appears ok checked again and still getting the same error
