my rainmachine uses a certificate "proxy2-1-us" which is causing my firewall some problems. 

Failed to authenticate cert num 1 in certificate chain for intercepted connection; Untrusted Issuer:/C=RO/O=rainmachine/CN=rainmachine-root-ca

for server address 54.187.30.66

the firewall is blocking all communication with this server because of this error.

if this server is using a self-signed certificate, shouldn't it be replaced with a valid signed certificate chain?
