lhttp error 1500 please help

[stu]

hi all i have tried to set up a Lhttp for the last few weeks on and off , and at the moment i get an error of 16#8601 in the subfunction status there is a number 16#0000_80C5 how can you find out what this means?
i have got the Lhhtp_get instruction executing , and the url address i have been giving by the IT and i can Get that info in a web browser to work ?

does the connection of the external security have to be allow Http or Https or can it just be s7 connection ive tried both and still the same numbers in the status and sub function status ?

any ideas
