i am using F5 for NLB, and i have the VIP pining, i have exchange 2010 on premise i think more than 10 servers
i installed all office 365 required servers for a hybrid configuration and what i am trying to do now is to make these servers HA, so i am adding an ADFS and ADFP and hybrid, now after adding the second ADFS by installing the ADFsetup_64 and the rollup 2, i am trying to access the three links, the link pointing to the primary, secondary and the nlb name, the primary is working but the secondary link is giving me this 503 error, it looks like a cert issue but i am installing the same certs as the primary
