This is probably your server limiting POST payload size. Try to raise that limit and it should fix that.

@Tony-Gavin What solved this issue for me was to edit the php.ini file located on /etc/php/7.0/apache2/php.ini (Debian 9 in my case) and increase the value of the max_input_vars parameter, by default the value was 1000 on my system I increased it to 10000. After this I was able to connect more than 100 edges (actions).
