SMTP notify failure on startup

Has anyone noticed that their SMTP notify is failing to start after updating to 0.100? My SMTP has not been working anymore after the update. On the logs I only get this:

Error setting up platform smtp
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/smtplib.py", line 387, in getreply
    line = self.file.readline(_MAXLINE + 1)
  File "/usr/local/lib/python3.7/socket.py", line 589, in readinto
    return self._sock.recv_into(b)
  File "/usr/local/lib/python3.7/ssl.py", line 1071, in recv_into
    return self.read(nbytes, buffer)
  File "/usr/local/lib/python3.7/ssl.py", line 929, in read
    return self._sslobj.read(len, buffer)
socket.timeout: The read operation timed out

During handling of the above exception, another exception occurred:

  File "/usr/local/lib/python3.7/smtplib.py", line 391, in getreply
    + str(e))
smtplib.SMTPServerDisconnected: Connection unexpectedly closed: The read operation timed out

It was working fine before the update but I did not find anything related to notify or smtp on release notes…

No problems here with smtp notify on 0.100.2.

After multiple reboots its seems to have gone back up. Nothing changed on my side so there must have been something else wrong.
