Radicale server with SSL - holian - Oct-09-2018

Masters,

When IOS12 update installed on Iphone not sync anymore the contacts, and can't configure Cardav account on IPhone (without SSL?).

What i done already:

install python
installed new radicale
make config file (auth: htpasswd)
configure SSL (make certs..with openssl..)
On localhost i can log in to the web interface...

On my iphone try to configure CARDAV as the following:

> server: myserver.com
> user: admin
> pass:admin
> SSL
> Port: external port of the router (DSN-NAT to intranet)
> URL: https://myserver.com:EXTPORT/admin/

In the radicale configuration file i use the following:

[server]
SSL = True
certificate = c:/radicale/ssl/server_cert.pem
key = c:/radicale/ssl/server_key.pem
certificate_authority = c:/radicale/ssl/client_cert.pem
protocol = PROTOCOL_TLS
[auth]
type = http_x_remote_user
htpasswd_filename = c:/radicale/htpasswd.txt
htpasswd_encryption = plain
[rights]
file = c:/radicale/rights.txt

On the router i see the packages, and in the command window (radicale run in debug mode) i see the following when try to connect from phone:

Quote:C:\Users\holian>py -m radicale --config "c:\radicale\config" --debug

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "C:\Users\holian\AppData\Local\Programs\Python\Python37-32\lib\site-packages\radicale\__init__.py", line 197, in process_request_thread
raise RuntimeError("SSL handshake failed: %s" % e) from e
RuntimeError: SSL handshake failed: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1045)

I really apperitiate any help how to make the connection work...

Regards

iPhones have a c:/ drive? Unless something's radically changed, I don't understand how that could work.

It looks like the new iphone version uses a new version of openssl, but radicale/python is using an old version. Have you tried running [iocde]pip install --upgrade radicale[/icode] to check for updates? I don't know what package manager the iphone uses, but there might be some flavor of apt/yum, and you could check for python-openssl updates?
