Failed to Authenticate to Osbot Servers

[sevant]

I am trying to download / run Osbot on a VPS with CentOS 6.10 installed. 

I am able to download osbot from the login screen. However, when I enter my login credentials (which I have double checked are correct) and click on "install webwalking", I am given the error "failed to authenticate to osbot servers".

 

It looks like other users have had this issue over the years, but have not seen any solutions posted in the threads. 

I am able to run other bots and have verified that I have internet connectivity.
