Hi there.
First of all, I'd like to say thanks for your library.
I have a problem, that is, I'm only able to get the TTS link only once in a loop.
Once, the next loop comes in, the TTS library either takes a very long time to generate a link, or, just doesn't generate a link at all.
I've also edited the original library, so that it uses setInsecure instead of setFingerprint.
Only thing I've found is that the WiFi client is stuck at 0 on the next iteration. (while (client.available == 0))
