We have moved our website from http to https. Whenever we tried to access https version's robots.txt it showing 404 error. All other URLs are working fine. Developer working on this issue to resolve. Seems its a time taking process. So temporarily we thinking to
1) redirect https://website.com/robots.txt
(Only this URL. All other URLs will be in https ) Or
2) Fetching robots.txt from http verified property in GSC
Can we do this? How google react? Is this is preferred by google?
