2. Go to System Properties → Advanced → Environment Variables. Under System variables, add E:\xampp\php as a separate entry in Path and verify the OpenSSL settings below.
   System variable    Value
   Path entry to add    E:\xampp\php
   OPENSSL_CONF    E:\xampp\php\extras\ssl\openssl.cnf
   OPENSSL_MODULES    E:\xampp\php\extras\ssl
3. Restart the Apache service on the affected FileCloud web server.
Retry the affected user’s login and verify that the error does not recur.
