I have 3 Esxi 6.7 hosts on Essentials Plus licensing. Using standard switche. All connextend to shared NAS storage.

only one of the three hosts successfully connects via iSCSI own connection. The other two esxi 6.7 hosts cannot connect To the same NAS datastore. . All host configured identically

what may be wrong?  Why does only one host connect to the NAS while other two will not.

vCenter 6.7 connects successfully to NAS DATASTORE
