Broken Certificate Validation

Help & Support
#1

I’m running Sonarr 3.0.6.1342 on Synology DSM 7.0.1-42218 and I’m getting an “Unable to communicate with SkyHook.” error when trying to add a show. Likewise, I’m getting a “Failed to fetch updates” error when viewing the updates page.

I reinstalled and I’ve done some searching and this appears to be a certificate issue (when I disable Certificate Validation in the General settings, everything seems to work OK, but this isn’t a good solution). How can I fix this?

Not a Sonarr issue

You need to update and sync Mono’s certs

Thanks for your reply. How can I do that? If it’s a Sonarr dependency, it’d be good to know.

Actually, I found the solution here in case someone needs it:

SSH in, then run this:

sudo /volume1/@appstore/mono/bin/cert-sync /etc/ssl/certs/ca-certificates.crt

Then restart Sonarr.

Worked a treat on my DS720+ running DSM7. Thanks!

Thanks for this. I had trouble with both the indexers and the Updates on Sonarr. "Couldn’t fetch updates’ or something like that.
The logs said “Error: TrustFailure (Authentication failed, see inner exception.)” and then looking at the inner exception it wrote “routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED”.

I SSH into the NAS, ran the command and everything went back to normal.

Cheers
