i have a question about the HTTP UPDATE example
i am trying to update via FOTA with the HTTPUPDATE example
in the following line:
t_httpUpdate_return ret = ESPhttpUpdate.update("http://server/file.bin");
i tried writing a direct link to my file that i place in dropbox :
https://www.dropbox.com/s/6okhpgdi33kk6 ... k.bin?dl=0
the browser on my pc downloads the file with no problem when i am logged in but the esp gives me an error:
HTTP_UPDATE_FAILD Error (-1):HTTP error: connection refused

my question how it can be acheived?
maybe using some other file hosting?

thanks in advance

I know it is long ago that you have posted this. It would be interesting for me if you ever got an answer or if you ever solved the problem. I am working on the same problem in vain.Always getting the same error: connection refused. Searched the WWW for weeks but no result yet.
Would be nice if you could give me a short note.

Sorry. I forgot to check Notify
