[Common Man]

I do my own scraping of episodes from the TVDB as I a manage which files I already have or do not have..


There is functionally nothing wrong with the TVDB API it is an SSL issue from the scraper accessing the TvDB API...
 I had to update my c# code (snippet below) to use .Net 4.5.2 (or plus) and implicitly set the security protocol to TLS12 v3 (code snippet below), SSL3 and TLS v1 & v2 is deemed not secure anymore 


...
apiCredentials _oCredentials = getCredentials();
                JWT.DefaultJsonSerializer s = new DefaultJsonSerializer();
                System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
                string newRequestUrl = Configuration.EndPointAddress() + "/login";
                HttpWebRequest request = WebRequest.Create(newRequestUrl) as HttpWebRequest;
                request.ContentType = "application/json";
                request.Method = "POST";

I don't think anything in Kodi is using SSL still. The above is irrelevant for the scraper here. Note that these current scrapers are just XML declarations and the core engine does all the fetches, etc as common functionality.

Monitor the Plex forum on this. A lot of useful information on the progress as they are working closely with TVDB (they have a business model to protect from failures like this). All the metadata seems to be flowing as it should now but ArtWork is still not being fetched due to issues at TVDB.

It is not clear yet that the TVDB scraper needs to be updated in any way once the dust settles at TVDB for it to function normally. The IT process at TVDB seems amazingly amateurish to me in this day and age but it is what we have.
