Description of issue: “Suddenly” Sonarr won’t connect to NAS using IP addresses, only hostnames

Suddenly 2 days ago, Sonarr started reporting that the connection to my download client was unavailable. The only log msg was “Unable to retrieve queue and history items from Sabnzbd NAS via etc hosts name” and the episode download job just sat in the Activity queue pending. A manual test of the download client connection also timed out.

My sabnzbd client runs on my synology NAS which is on my LAN (same subnet as my Sonarr box) and I could connect to it and download files manually so no problem there. After a LOT of changing settings, re-installing Sonarr and dropping back to a very basic setup I’ve found that entering an IP address in the host field of the download client dialog no longer works and it must be DNS name. I had to create an entry in my Windows hosts file and use that. Having fixed that, I then also discovered that my Remote Path Mapping entry, which also uses an IP address, also had to now be changed to a DNS name.

My system has been working seamlessly for over a year using the IP address entries so I’m at a loss about why it’s suddenly stopped. Has anyone else experienced anything similar and know why this happens?

thnx

Could it be your IP changed ?
Did you check that first ?

It’s a static IP and as I mentioned I was able to connect to my sabnzbd client manually and download fine.

from an escalated cmd prompt do; (replace a.b.c.d with the nas ip address)
ipconfig /all
ping a.b.c.d
tracert a.b.c.d

anything weird with those?

power down the machine and do a cold start?

All checked out previously. Connectivity to my sabnzbd client outside of Sonarr is working fine.

6

do you run sonarr as a service or a scheduled task?

can you run sonarr manually (as yourself, not a service) and see if it has any issues connecting?

I run it as a service but just tried it manually under my login credentials (which have admin rights) and still doesn’t work with an IP address.

I’m no longer too concerned about it since I now have it working using a hosts file entry. I was just curious if someone had come across a similar problem and new what the reason for it was.
