I asked my host provider to check
max_allowed_packet

wait_timeout
or any variable make MySQL server has gone error and he said that everything is ok.

I made test with googletest.php file and the result is

Starting translation test
Test result: {"responseData": {"translatedText":"mile widziane"}, "responseDetails": null, "responseStatus": 200}
Test error: 
Connection time (ms): 39.6818847656
