This is more to let users know about a limitation with adding in a webclip in System Manager.
We have a web service for a 3rd party product that we connect to using a specific IP and port in a web browser i.e. 192.168.1.1:123
I dont know if the limitation is with Apple or Meraki but URL's cannot include colons ( : ), the only way around this I see is to manually bookmark the address in Safari.
