VMWARE ISCSI Issues

I have 3 ESXi hosts that connect to 3 different LUNS on a Equalogic.  

Today I logged into vcenter and noticed some errors for one of the hosts.  It seems it was diconnected from the datastores.

So I tried to reconnect it without any luck.   I even wiped the configuration of the host and tried configuring it from scratch.

The error I am getting in the equallogic is:

ISCSI login to target "*****" from initiator "******" failed for the following reasons: Initiator disconnected from target during login.

Any help would be appreciated.

@hanccocka
How do I check the ESXi host logs?

@IanTh
Web update??  I have been using update manager.

I did try restarting the esx host, even wiped the config out and rebuilt the config.

I seemed to have fixed the issue.

I don't know why this happened but it seems "Header Digest" was set to required, I changed it to prohibited and now all is well!
