Why does Google swear at robots.txt?

Question

Google

Google does not index the site, referring to the blocking in robots.txt. Although there is no blocking for indexing in robots.txt. I set the following directives (and also tried many other different options):

User-agent: *
Allow: /
Dissallow:

I even deleted the robots.txt file itself, but Google still gives this error. Those. the file didn't directly exist, but Google referred to a lock in it.

Is there anyone who can tell what's going on?

Answer 1

Remove Dissallow :

Answer 2

Dissallow: misspelled. Disallow required.
