Strange entries in my access.log

Hi

While investigating th eproblem that I am seeing about “getting stuck”, I was looking at my
nginx access.log and found some alarming entries…

Are these just attempts into my server ?

I have tried spending a bit of time making my server a bit more secure…
e.g. blocking root access on SSH…etc
and also using HTTPS (instead of HTTP) with a SSl certificate.

So I thought my server should be reasonably secure ??

These are all search engine web crawlers used for indexing your site.

Nothing to worry about (unless these files are meant to be private? :thinking:)

Thank you Ankush !

I have spent a bit of time to secure my server a bit … .closing up the firewall. But I think I need
to close down the IP range that can access it as well. Just awaiting info from my ISP as to their IP-ranges that they assign.

Appreciate your time !!!
