WebDAV warning about 'SSL error'

epsicot · 13 Sep 2013, 06:36 PM

Hello,

I am using a third-party program (namely duplicity, a python program) to send backups to myfiles.messagingengine.com via webdavs.

My version of duplicity has not changed in a while, but these messages have started to appear
(they do everytime I run the program to connect to this server):

Code:

WARNING 1
. Attempt 1 failed. SSLError: The read operation timed out

Operations complete normally afterwards.

Do you have any idea what might be wrong ?

Fastmail upgraded their SSL security setup on Aug 9, 2013:
Fastmail uses perfect forward secrecy with https/TLS connections

Secure connections have to negotiate on which common method both ends support. My guess is that this might take a bit longer with the new SSL setup. Hopefully Rob N or Bron from Fastmail will comment.

Sounds likely to me. I don't know 'duplicity', but we have indeed both changing our SSL settings in nginx, and also switched to using nginx in front of apache (we used to have apache on the internet directly for DAV because of chunked encoding uploads - but nginx supports them now)

Hopefully an updated version of duplicity will fix this.

Could duplicity be caching old settings, causing dificulties with the new Fastmail setup?

@n5bb I am not aware of any such cached setting.

I tried again with duplicity 0.6.22 instead of 0.6.21 and these warnings still appear.

I don't see these error messages anymore with duplicity 0.6.24
