Solution:
Dear Sir/Madam
For this issue, First, check the ERA Explorer and ERA Server an updated version is present or not. If not then update it from the below link(http://eralms.mkcl.org/)
Close the Firewall and IPversion6 (IPversion6 is present in Network and Sharing Center option in the control panel) disable the antivirus and net-protector.
In case of any query kindly raise the support ticket for the same.
