Regenerate indexes in Algolia

I am using magento 2. At first Algolia reindex was working fine after configurations. I had to clear all indexes from the algolia dashboard and after that tts not regenerating all data.

Can you help me how i can add data to algolia again?

Hello @chris2,

did you try to reindex again? Can you see any error while you reindex?
Do you have indexing queue enabled? If so, did you set up a cron job to process the queue?
