S2S IPsec FortiGate Wont come up, Can not ping 2 of the 3 sites from FG or Windows

Hi all! Still learning the FortiOS and have run into a issue and its time critical i get it fixed ( Sites need to print Paychecks tomorrow ) 

So 2 of my 3 tunnels when down and i started with trying to ping the Public IPs and sure enough from CLI Fortinet/windows i can not ping those public IPs but if i log into the comcast modem can ping the public IP addresses and if i go to the other 3 sites and ping the Main sites IP that come back as responding from Fortinet/Windows and the Modems. Any ideas on what may have gone down or broke?

Any help is appreciated!
