The json is only 320 KB. 10 sec should be more then enough even with a slow internet connection. Your second screenshot indicates that you have no connection at all. Please check my previous post, it's a good workaround using a local server. You have to download the opm.zip only once.
PS: Nowadays a good internet connection should be something trivial. I also leave in a pretty crappy country, still the internet speed is very good.
Ok I will try and downloading...
So actually I can do all of this manually of course but when I use any software I am looking as a end user even newbie developer.
If happen any unwanted step in my software as looking end user it will be happen again...
I collect another warnings too when attemp to connect from lazarus to
http://packages.lazarus-ide.org/.
Lazarus going to go endless loop.
But I am downloading opm.zip with by firefox there is no connection problem this means there is a/some problem(s) in the package man.
However I will change the my local codes if I get success I'll share.
I also will try to local web server too.
