BlockingIOError: [Errno 35] Resource temporarily unavailable

[chabanovsky]

After the last update from the upstream I get the following error each time (as I understand) when I lose an internet connection (for example, a pc goes to hibernate mode and back or a router reassigns an IP–address). After the exception the app stop receiving updates.

Exception in thread UpdatesThread:
Traceback (most recent call last):
  File "/development/Telethon/telethon/network/tcp_client.py", line 80, in read
    partial = self.socket.recv(left_count)
BlockingIOError: [Errno 35] Resource temporarily unavailable

During handling of the above exception, another exception occurred:

Well this also happened on #47 so maybe if this happens I should try disconnect and then reconnecting?

I'm not sure if this will work, but at least it's worth a try.

Those timeouts are probably related to #94 @chabanovsky. Can you please test the upstream version too?

There are a few newer issues also mentioning both Errno 35 and Errno11 (causing TimeoutError). Discussion has been moved there. Also, check your system time and the wiki front page.
