SSL Verification error | can't even install fix common problems plugin

[DaHunni]

I always get the SSL verification failure message when trying to install a plugin and I just can't find a way arround it. I just want the dvb plugin to downgrade to a not totally unusable version but since I cannot even install any plugins there is no way to fix my entire unraid.

I also more than tripple checked my date and time settings.

 

Is there no way arround the ssl verification with the wget commands or is there any way to get the certificates right?

Post diagnostics. 

 

Usually this is caused by time being wrong or DNS. If you're sure those are correct, reboot your server to see if that clears things up.
