There's not much I can do about an SSL certificate expiry. SSL certificates are managed by Kodi and the certificate issuer. If the website's SSL certificate has expired or Kodi can't authenticate it with the certificate authority or the certificate has expired in Kodi's cache then Kodi will refuse the connection as a safety precaution.

If a connection is refused, TMDbHelper suppresses making further requests to that API for a short period to avoid continually trying to re-request data from a server which isn't responding for whatever reason.

You can read more about how Kodi manages SSL here:

Sorry, I did not mean it was something you should be solving, not necessarily, I mean. If fanart.tv certificate has indeed expired I suppose it's all on their end. What surprised me is that if I used my browser to navigate to https://webservice.fanart.tv, the certificate there did not look expired. With the certificate (issued by Let's Encrypt) valid till Mon, 18 Mar 2024 03:32:54 GMT.

So something is... "strange" in the scenario? I posted here because I wanted to understand if this was a problem just on my end or if others were experiencing it. Also, is there something I could do from my end to gather more information regarding the error message (maybe an option in logging, to see what certificate Kodi is getting, compared to Firefox)?
