SSL connection crashes Sonarr after mono update

[napchar]

Sonarr version (exact version): 2.0.0.4472
Mono version (if Sonarr is not running on Windows): 4.6.2 (Stable 4.6.2.7/08fd525 Wed Dec 7 20:01:26 CET 2016)
OS: Synology DSM 6.0.2-8451 Update 7
((Debug logs)): https://dl.dropboxusercontent.com/u/11428780/SonarrLog.txt
Description of issue:

Hi,
Since the last update of Mono I have an issue when connecting to sonarr over https (port 40120).
Attempting to connect causes Sonarr to crash/stop and I have to manually restart the app.
Connections over http (port 8989) still work fine.
Any help would be greatly appreciated!
Cheers,
Filip

We’ll need to see ((debug logs)) to investigate further, though mono actually handles the SSL connection, so there may be nothing we can do.

Debug log can be found here: https://dl.dropboxusercontent.com/u/11428780/sonarr.debug.txt
Doesn’t contain much more info then the standard log I’m afraid.

Mono.Security.Protocol.Tls.TlsException: The client stopped the handshake.

Interesting that the client stopped it, but perhaps it didn’t like the available TLS options (Mono’s support for SSL has been pretty poor until recently, but not sure if the new changes are applied automatically).

I’d take a look at the reverse proxy available in DSM 6 (Under Application Portal), which uses apache or nginx, both of which support the latest TLS versions.

Same issue here!

Seeing this as well. Is there a setting in mono that can be changed to re-enable it? Or any additional information that can be provided to assist with troubleshooting?
