Thank you for your responses.
Actually, I can't do anything in the server side because it's managed by
an external service provider. I don't know what server are they running
but I'll try to find it.
I thought the problem was in the client side, but now I think I'll try
to ask them to solve the problem. Retrying the requests could be a
problem if the server really receives and processes them.
I'll tell you about this issue when I know new matters.
