tts.save() is taking too long when running on remote linux server

[clairerity]

Hello! First of all, thank you for this wonderful package. I would just like to ask why is it everytime I run tts.save() using my remote linux server (SSH, ubuntu), it gets stuck on "sock.connect(sa)". My gTTS version is the latest one (2.2.3) and python is 3.8.

My code is very simple:

from gtts import gTTS
tts = gTTS('hello', lang='en')
tts.save('hello.mp3')

the first 2 lines work very fast but when i run "tts.save()", the wait time is too long (around 15-20 mins) and when i interrupt it, this is the error:

KeyboardInterrupt                         Traceback (most recent call last)

Hoping to resolve this problem as I really need this for school. Thank you very much in advance!
