Sonarr Can't connect to anything - Windows

[MrZippy]

So… I had been using Sonarr on Windows for Months… and now all of a sudden, it stops working. It can no longer connect to my SABNZBD+ on the same machine, or any indexer. Fails the test every time. I’ve tried removing, reinstalling, restoring from backup, and still it’s the same thing. I don’t have any issues connecting to the net or other resources on my network, just Sonarr seems to be broken.

Logs are littered with error messages like this:

Request Failed: Unable to connect to the remote server

So… I found the source of the problem.

This tipped me off:

Sonarr/Sonarr

A recent update must have changed the way it interacts with my computer. Once I changed the NZBDrone to logon using my account (instead of System) it started working correctly again.

@MrZippy

machine actively refused it 127.0.0.1:63505

you sure you dont have some dodgy proxy running there? or is 63505 the port of sabnzbd?

[MrZippy]

That’s just it… SABNZBd uses port 8085… but it was the service credentials. Once I changed from system to a user on the machine, it works fine. Go figure.

[dan]

yea, but the reply is as if there is a proxy service running, so you might want to scan your system for malware etc

theres no reason that should not be working under the previous setup, what you did might have just worked around the problem but not solved the cause
