Sonarr version ([v3.0.1.430]):
OS: Win 2012 R2 64x
Debug logs: https://pastebin.com/QZuKqQ5y
Description of issue:
The underlying connection was closed: An unexpected error occurred on a receive. —> System.Net.Sockets.SocketException: No such host is known
Please upload the log files, don’t paste them in a google doc which will mess with the formatting.
The error could be DNS related, but what address are you trying to use?
Done logs are at pastebin now.
Tryed my 192.168.1 adress and 127.0.0.1 and localhost have it on a local pc
also use radarr and there are no problem.
What host was used when you got that message? Or do you get the exact same error for all of those?
its the same for all
I’ve push ed a new build that should address your issue, please give it a shot when it’s available (3.0.1.435 or later).
sry markus101 that did not do the trick. 3.0.1.435

Thanks, found the issue, the hostname was being combined with the port so DNS lookups would fail, that will be fixed in next release.
Thank you so much 
still a little problem: Unknown exception: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Have you disabled certificate validation for local addresses in Sonarr’s general settings?
no that was enabled, work now when disabled for local, thanks
