Hi! Thanks for your answer and your help.
I found what was the problem and I'll say what I did in case anyone have the same issue.
After migrating from Hyper-V to VmWare, I had to reconfigure the trust certificate between the server that WAP (web application proxy) is installed and the ADFS server.
Some windows services related to ADFS wasn't being able to start without this reconfiguration and I could see this issue on event viewer.
But that was not enough. In VMWare, I had to change the type of my network adapter from "VMXNET3" to "E1000E".
To be honest I don't know why I couldn't use the VMXNET3 adapter, but is working fine now with the E1000E.
Thank you for your suggestion and pacience.
