use your Jackett Dashboard to edit (click the Wrench Icon) your YGGTorrent Indexer.
set your Site Link to https://www.yggtorrent.ch/ and your search link to www2.yggtorrent.ch and click OKAY.
if you get an error, click CLOSE and try again. it should save the second time.
if you cannot make it work, use the trashbin Icon to delete it and fetch it new from the add-indexers page. It should be preloaded with the correct details.
Thank you @garfield69 for the trick
same for me thanks @garfield69
