Can not connect to tcp server content_IP "162.125.5.8"

[PavelBabak]

I use ESP8266 module with Arduino Dropbox Manager library.  Previously, everything worked well. Yesterday I found that the client cannot establish a connection to the server. Communication with main_API "162.125.5.7" is successful. But communication with content_API "162.125.5.8" is unsuccessful. 

When trying from a PC ping to main_API "162.125.5.7" is 153 ms, ang pind to content_API "162.125.5.8" fails timeout.

I do not know where these addresses are taken from in the library.

Please help to solve the problem.

The Dropbox server IP addresses are subject to change, so you should never rely on hard-coded IP addresses. You should use the hostnames instead. For the main API servers, that's 'api.dropboxapi.com'. For the content API servers, that's 'content.dropboxapi.com'. (You can find the relevant hostname for each endpoint in the documentation.)

Please change your code to use the hostnames instead of hard-coded IP addresses.
