Today I was working on my Test environment i got this issue -
I was trying to ssh form one Esxi to another and I got below error
FIPS mode initialized
I never had this issue earlier .. I also could not find a KB, just found this post on vmware community
and it resolved my issue..
All i had to do is disable firewall on both esxi hosts.
esxcli network firewall set -e false
it worked like a charm. Thanks
