Can't connect to any indexers after updating Synology package

[Mike_Leone]

I’m running Sonarr as a package on Synolfy DSM v7 (i.e., not using Docker, I am using the community package). Today I update my Sonarr to the latest available (3.0.6.1265, Mono 5.20.1.34). Now all my indexers are failing. Log shows:

2022-10-10 16:15:08.2|Warn|SonarrErrorPipeline|Invalid request Validation failed:
– : Unable to connect to indexer, check the log for more details
2022-10-10 16:17:40.5|Error|X509CertificateValidationService|Certificate validation for https://api.nzbplanet.net/api?t=caps&apikey=(removed) failed. RemoteCertificateChainErrors

I don’t know why it says the certificate validation failed, if I g to the URL (https://api/nzbplanet.net) manually, the certificate icon shows fine and valid.

I’m getting the same problem on any indexer (nzbplanet.net, drunkenslug.com, nzbgeek).

Is this just me? I am searching, but not finding anything relevant. I did see this, from late 2021:

Mono, Let’s Encrypt root certificate expiry, DSM 6.2

Synology Community

about updating mono certificates, which I did do, last year. Do I need to do that again??

Thanks for any help.

Yes. Based on the error and also previous related errors and the fix, it is the same Syno mono cert issue and will require the same/similar fix as before.

Ok, thanks. But I did this:

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

And it didn’t resolve the issue. I did stop and start Sonarr package.

Indexers are still working for Radarr, so I know it’s not a problems with the indexing site themselves. It’s only Sonarr that’s having the issue.

I think you need to follow the full steps per the wiki, which includes the extra chmod command

https://wiki.servarr.com/sonarr/installation#synology-mono-ssl-errors

sudo /volume1/@appstore/mono/bin/cert-sync /etc/ssl/certs/ca-certificates.crt
sudo chmod -R a+rX /usr/share/.mono

[Mike_Leone]

That was it! I did the “chmod” command, and then the indexers started to work!

Thanks so much! This is why I’ve been holding off on updating Sonarr on Synology, this is the 2nd time I’ve been burned with this same cert problem.
