google_places Error in value[[3L]](cond)

[naggefreschle]

I'm using google_places() in a loop. It works fine for most of the searches. But sometimes I receive such an error.

Error in value[[3L]](cond) : 
  There was an error downloading results. Please manually check the following URL is valid by entering it into a browswer. If valid, please file a bug report citing this URL (note: your API key has been removed, so you will need to add that back in) 

https://maps.googleapis.com/maps/api/place/textsearch/json?query=EIH+LTD+(+THE+OBEROI+GRAND)+15,+JAWAHARLAL+NEHRU+ROAD+++ESPLANDE++700013+Kolkata&key=

Entering the URL in the browser brings a result.
As it work in most of the cases it cannot be a proxy issue right?
I tried converting to UTF8 as well.
This is what I found as possible solutions, yet.
