I've been having issues with Skype constantly going offline. I can go back online when I notice but it usually does this several times a day. I'm using the Skype Web plugin v0.12.2.2 with Miranda NG Version: 0.95.5 alpha build #15967 x64.
Usually I see something like this in the logs when it's connected:
[11:16:31 1DF4] [SKYPE_1] (1104) Connected to bn1-client-s.gateway.messenger.live.com:443
[11:16:31 1DF4] [SKYPE_1] (1104 bn1-client-s.gateway.messenger.live.com) Starting SSL negotiation
[11:16:38 1DF4] [SKYPE_1] (1104 bn1-client-s.gateway.messenger.live.com) SSL negotiation successful
Occasionally the SSL connection fails and I go offline. It reports "Failure to negotiate SSL connection".
[11:17:17 1DF4] [SKYPE_1] (1104) Connected to bn1-client-s.gateway.messenger.live.com:443
[11:17:17 1DF4] [SKYPE_1] (1104 bn1-client-s.gateway.messenger.live.com) Starting SSL negotiation
[11:17:23 1DF4] [SKYPE_1] (1104 bn1-client-s.gateway.messenger.live.com) Failure to negotiate SSL connection
I didn't have the issue with the standard Skype client. There is no proxy in use although the plugin's network settings are set to the default Internet Explorer. 
Is there anywhere I should start to see what is causing the issue? I can attach or send more of the netlog I saved but the above seems to be the jist of the issue; it's periodically unable to establish an SSL connection.
