I registered with Cloudflare and it shows as active but when I put URL with https://www.fromthemurkydepths.co.uk in browser it comes up as non secure. If I click advance then proceed it then takes me to a completely different webpage!
That would suggest you have the IP hardcoded in your hosts file and the DNS resolution doesnt work at all.
You should remove the hosts entry and as far as DNS is concerned, there is either an issue with your DNS resolver or it is a propagation issue. That is difficult to say at this point.
This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
This file contains the mappings of IP addresses to host names. Each
entry should be kept on an individual line. The IP address should
be placed in the first column followed by the corresponding host name.
The IP address and the host name should be separated by at least one
space.
Additionally, comments (such as these) may be inserted on individual
lines or following the machine name denoted by a ‘#’ symbol.
For example:
All right, it does not seem to be a hosts issue then but seems to be related to DNS, though it is weird nslookup wouldn return anything. You’d need to debug your network setup at this point but I am afraid that will be a bit beyonnd the scope of the forum here.
