Google Search Console reporting 5xx error

Hi there, I recently migrated this site from Joomla to WP and the hosting to you guys. The site was ranking #1, P1 for the keyword “deep sea fishing sydney” it fell for a bit but it’s back up there.

My question is Google are reporting a large number of 5xx error but they are all to http: urls and now the whole site enforces https: and the submitted sitemap has no http: urls.

Is it safe to just ignore this or how to I tell Google to stop trying to index http?

Thanks

Peter
