HTTP request sent, awaiting response... 502 Bad Gateway about sentinel-download HOT 3 CLOSED

Hi,
yes, it happens from time to time (not only to you ;) ), and seems to be caused by the ESA server.
I have just tried to trap the error (because at the beginning, the file was ignored, but was missing when one tried to use the tile).

Another solution could be to try again the file download. But how many times...

After downloading 64 tiles, I did not encounter a problem when using:

while os.path.getsize( [path to downloaded file] )==0 :
    os.system(commande_wget)

I just added this after every os.system(commande_wget). Every time I have had 502 Bad Gateway the first retry succeeded. It would probably a good idea to use something like this:

max_tries = 3

for i in range(max_tries):
    os.system(commande_wget)
    if os.path.getsize( [path to downloaded file] ) > 0:
        # download succeeded
        break

This way I can be more confident about the script will succeed.

Good idea, i have generalized adding

while os.path.getsize( [path to downloaded file] )==0 :
    os.system(commande_wget)
